In a certain country store, there are three kinds of bottled drinks. A cola, which costs $3, a juice for $1.5, and water for $1 per bottle. One day the store was able to sell 15 bottles of cola, 25 bottles of water, and 12 bottles of juice. How much did the shop earn?
Thoughts? Step-by-step reasoning:
15 bottles of cola is a cost of 15 * 3 = $45. 12 bottles of juice make up to 12 * 1.5 = $18. As each of the 25 sold water bottles was $1, the shop made a total of 45 + 18 + 25 = $88.
Thus, the answer is 88.
