Try to solve each of the following. Click the Check Me button to check each solution. You will be told if your solution is too short, has a block in the wrong order, or you are using the wrong block. Some of the problems have an extra block that isn’t needed in the correct solution. Try to solve these on your phone or other mobile device!

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. But, 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 Me button to check your solution.

        miles = 200
price = 2.20
mpg = 42
---
numGalls = miles / mpg

cost = numGalls * price
---
print(cost)
---
print(totalCost) #distractor

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. But, 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 Me button to check your solution.

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

The following program segment should print how many chicken wings you can buy with $3.50 if the wings are $.60 each. But, 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 Me button to check your solution.

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

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. But, 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 Me button to check your solution.

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

The following program segment should print how much each pair of shorts cost when they are buy 2 and get the third free. The shorts are originally $39.99 each. But, 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 Me button to check your solution.

        price = 39.99
---
priceForTwo = price * 2
---
itemPrice = priceForTwo / 3
---
print(itemPrice)
---
itemPrice = priceForTwo / 2 #distractor

Arrange the code so the following is displayed in order: 55, “computer science”, 0. 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 Me button to check your solution.
