Question

Liah is ordering 5 identical sandwiches and a bag of chips. The bag of chips costs $1.25, and the entire order costs $38.75. Write an equation you can use to find the price of a sandwich.

Answer 1

Equation: 1.25 + 5s = 38.75

Price of 1 sandwich = $7.50

Explanation:

If all 5 sandwiches are identical that means we can represent one as "s".

Since the total is 1.25 (for the chips) + 5 sandwiches

We can write the equation:

1.25 + 5s = 38.75

Now we can solve for the cost of one sandwich s.

Subtract 1.25: 5s = 37.5

Now divide by 5: s = 7.5

So one sandwich cost $7.50
