Question

camille spends the same amount of money on lunch every day. on monday she bought a sandwich for 4.25 and two orders of fries. On Tuesday she bought a hamburger for 6.75 and one order of fries. What is the cost of one order of fries?

Answer 1

One order of fries costs 2

Explanation:

She got 4.25 + two fries on Monday

She got 6.75 + one fries on Tuesday

Since she spends the same amount of money on lunch every day, both of the money that is spent must be equal.

Let f represent the cost of one order of fries, then equations can be written as follows:

4.25 + 2f (1)

6.25 + f (2)

Since both is equal:

→ 4.25 + 2f = 6.25 + f

→ f = 2
