print(perPersonCost)
---
print(perpersoncost)  #distractor

Checkpoint 14.12.3.

oInCup = 12
---
totalPunch = 2 * oInGallon
---
amountLeft = totalPunch % oInCup
---
print(amountLeft)
---
amountLeft = totalPunch / oInCup  #distractor

Checkpoint 14.12.4.

The following program segment should print the number of seconds in 5 days. However, the blocks have been mixed up and include an extra block that isn’t needed in the solution. Drag the needed blocks from the left and put them in the correct order on the right. Click the Check button to check your solution.

sInMin = 60
mInHour = 60
hInDay = 24
---
sInDay = sInMin * mInHour * hInDay
---
total = sInDay * 5
---
print(total)
---
total = sInDay / 5  #distractor

Checkpoint 14.12.5.

The following program segment should print the number of months it would take you to save 500 if you make 50 a week. However, the blocks have been mixed up and include an extra block that isn’t needed in the solution. Drag the needed blocks from the left and put them in the correct order on the right. Click the Check button to check your solution.

weeklyRate = 50
goal = 500
---
numWeeks = goal / weeklyRate
---
numMonths = numWeeks / 4
---
print(numMonths)
---
numWeeks = weeklyRate / goal  #distractor

Checkpoint 14.12.6.

The following program segment should print the cost of a trip that is 200 miles when the price of gas is 2.20 and the miles per gallon is 42. However, the blocks have been mixed up and include an extra block that isn’t needed in the solution. Drag the needed blocks from the left and put them in the correct order on the right. Click the Check button to check your solution.

miles = 200
price = 2.20
mpg = 42
---
numGalls = miles / mpg
---
cost = numGalls * price
---
print(cost)
---
print(totalCost)  #distractor

Checkpoint 14.12.7.

The following program segment should print how many miles you can go on half a tank of gas if the miles per gallon is 26 and your tank holds 15 gallons. However, the blocks have been mixed up and include an extra block that isn’t needed in the solution. Drag the needed blocks from the left and put them in the correct order on the right. Click the Check button to check your solution.

mpg = 26
tankHolds = 15
---
numGalls = tankHolds / 2
---
miles = numGalls * mpg
---
print(miles)
---
mpg = 15
tankHolds = 26  #distractor

Checkpoint 14.12.8.

The following program segment should print how many chicken wings you can buy with $3.50 if the wings are $.60 each. However, the blocks have been mixed up and include an extra block that isn’t needed in the solution. Drag the needed blocks from the left and put them in the correct order on the right. Click the Check button to check your solution.

cost = 0.6
money = 3.5
---
numWings = money / cost
---
print(numWings)
---
print(NumWings)  #distractor

Checkpoint 14.12.9.

The following program segment should print how much you will have to pay for an item that is 60% off the original price of $52.99. However, the blocks have been mixed up and include an extra block that isn’t needed in the solution. Drag the needed blocks from the left and put them in the correct order on the right. Click the Check button to check your solution.

price = 52.99
discount = 0.6
---
savings = price * discount
---
finalPrice = price - savings
---
print(finalPrice)
---
finalPrice = price - discount  #distractor

Checkpoint 14.12.10.

The following program segment should print how much each pair of shorts costs when there is a buy 2 and get the third free sale. The shorts were originally $39.99 each. However, the blocks have been mixed up and include an extra block that isn’t needed in the solution. Drag the needed blocks from the left and put them in the correct order on the right. Click the Check button to check your solution.

price = 39.99

priceForTwo = price * 2
---
itemPrice = priceForTwo / 3
---
print(itemPrice)
---
itemPrice = priceForTwo / 2  #distractor

Checkpoint 14.12.11.

Arrange the code so the following is printed in order: 55, “computer science”, 0. The blocks have been mixed up and include an extra block that isn’t needed in the solution.
