Answer:
<u>The correct equation form for finding the price of a sandwich is 5x + 1.25 = 38.75</u>
Step-by-step explanation:
1. Let's check all the information given for solving this question:
Cost of bag of chips = US$ 1.25
Cost of sandwich = x
Cost of total order = US$ 38.75
2. The formula for find the cost of sandwich (x) is this:
5x + 1.25 = 38.75 (Joaquin ordered 5 sandwiches and a bag of chips)
5x = 37.50 (Subtracting 1.25 at both sides)
5x/5 = 37.50/5 (Dividing by 5 at both sides)
x = 7.50
<u>The cost of each sandwich was US$ 7.50</u>
