Question

Suppose you brought 8 oranges and 1 grapefruit for a total price of $4.60. Later that day, you brought 6 oranges and 3 grapefruits for a total price of $4.80.What's the price of each type of fruit.

Answer 1

oranges $0.5 grapefruit 0.6

Explanation:

o = oranges

g= grapefruit

8o +1 g = 4.60

6o+3g= 4.80

Multiply the first by -3

-24o -3g = -13.80

6o +3g = 4.80

ADD BOTH (3g will be cancelled)

-18o = -9.00

o = 9/18 = 0.5

8(0.5) +1g= 4.60

4.00 +g = 4.60

g = 0.60

Answer 2

assuming the prices did not change during the day,

8o+g=460

6o+3g=480

18o=900

o=50

g=60

so, oranges cost $0.50, grapefruit cost $0.60
