Answer: $23.24
Step-by-step explanation:
This question assumes that each sandwich is 3 times the price of a bag of chips.
If a sandwich costs $7.75, a bag of chips would be:
= 7.75 / 3
= $2.58 per sandwich
The total cost of what Duff bought is therefore:
= (7.75 * 2) + (2.58 * 3)
= 15.5 + 7.74
= $23.24
