You are a volunteer for the school store. One of the most popular items is
strawberry-banana orange juice. There are two local vendors that will
deliver the juice to the school store at the beginning of every month.
Healthy Drinks, Inc. charges $0.39 per bottle with a delivery fee of $25. The
Squeeze charges $0.18 per bottle with a delivery fee of $65. Let C
represent the cost of purchasing bottles of juice from Healthy Drinks, Inc.
and b represent the number of bottles. Write an equation that relates C and
b for this problem situation. (Instead of using y and x you need to use the
letters c and b).
