Question

Miya is selling grapefruit and nuts for a fundraiser. The grapefruits cost 5 dollars each and a bag of nuts cost 15 dollars each. She sells 30 items and made 250 dollars. How many grapefruits did she sell?

Answer 1

A) 5G + 15N = 250

B) G + N = 30 We'll multiply B) by -5

B) -5G -5N = -150 then we add A)

A) 5G + 15N = 250

10N = 100

N = 10 bags of nuts ($150.00)

We put N=10 into A)

A) 5G + 150 = 250

A) 5G = 100

G = 20 Grapefruits ($100.00)
