Question

FL 7.EE.2.4

Answer 1

Answer:

The correct equation form for finding the price of a sandwich is 5x + 1.25 = 38.75

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

The cost of each sandwich was US$ 7.50
