Question

A. $0.55
B. $0.70
C. $0.75
D. $0.60

Answer 1

Lte A for apples, G for orangs
And write equation
2A +6G =$5.6, (tim*(-3))
6A +2G =$4.8
you can use elemate to solve or Subtitution
I like solve by elemate
-6A-18G=-$16.8
6A +2G = $4.8
..................Add
-16G = -$12
G = -$12/-16

G =$0.75
Subtitution G =$0.75 solve or A
2A +6(0.75) =$5.

2A +4.5=$5.6
2A=5.6-4.5
A = 1.1/2
A = $0.55
apples:$0.55 for each
orang: $0.75 for each
