Answer:
4 + 2.5c = 16
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
