Katie went to the convenience store to buy some snacks. She spent a total of $16.00 on soda and candy. The soda cost $4.00 and each candy bar cost $2.50. Write an equation that represents this problem.

4 + 2.5c = 16

Step-by-step explanation:

Let c = number of candy bars

All soda cost $4.00

Each candy bar costs $2.50, so c number of candy bars cost 2.5c.

The total cost is the sum of the costs of the soda and candy bars.

Total cost is 4 + 2.5c

To write the equation we set the total cost expression above equal to the given total cost.

4 + 2.5c = 16

answer: a and c are correct

step-by-step explanation:

the +5 is the vertical translation

the added negative symbol in front is the reflection over the y-axis

final total: 63

step-by-step explanation:

60 times sales tax

60 times 0.05

3

60 + 3

63
