To find the total cost of Jessica's side dishes for 15 days, you first need to calculate the cost of the fruit cup and the salad for one day, then multiply by the number of days.
Cost for one day:
- Cost of a fruit cup: \(0.75\)
- Cost of a salad: \(1.50\)
Total cost for one day: \[ 0.75 + 1.50 = 2.25 \]
Total cost for 15 days: \[ 2.25 \times 15 = 33.75 \]
Thus, the total cost of Jessica's side dishes for 15 days is 33.75.
