Question

Berny bought a soft drink for 2 dollars

and 6 candy bars. He spent a total of
20 dollars. How much did each candy bar cost
bar cost?

Answer 1

Answer: Each candy bar costs $3

Explanation:

Set variables

Soft drink = $2

Candy bars = $6x

• Let x be the cost for each candy bar.

Total cost = $20

Set equation

2 + 6x = 20

Subtract 2 on both sides

2 + 6x - 2 = 20 - 2

6x = 18

Divide 6 on both sides

6x / 6 = 18 / 6

x = 3

Hope this helps!! :)

Answer 2

3

Explanation:

Given:

Berny spent 20 dollars total

He spent 2 dollars on a soft drink

He bought 6 candy bars

Solution:

Amount spent on candy bars = total amount spent - amount spent on soft drink.

Amount spent on candy bars = 20 - 2 = 18

Cost of each candy bar = total amount spent on candy bars / # of candy bars bought

Cost of each candy bar = 18/6 = 3
