Question

Brianna bought a sandwich, apple, and cookie for lunch. The total was $5. if a sandwich costs six times more than the cookie, and an apple costs three times more than the cookie, how much does each item cost?

Answer 1

The cookie costs $0.50, the apple costs $1.50, and the sandwich costs $3.

Explanation:

I multiplied 0.50 by 3 (for the apple) and got 1.50, then I multiplied 0.50 by 6 (for the sandwich) and got 3. I then added them all together and got 5.

Answer 2

Cookie=0.5, Apple=1.5, sandwich= 3

Explanation:

Lets say cookie = x, then sandwich = 6x since sandwich is 6 times more expensive, apple = 3x. function: 6x+3x+x =5

10x=5

x=0.5
