Answer:
peach = $0.75, mango = $1.75
Explanation:
Let p be the price of a peach and m be the price of a mango, then
5p + 7m = 16 → (1)
10p + 4m = 14.5 → (2)
Multiplying (1) by - 2 and adding to (2) will eliminate p
- 10p - 14m = - 32 → (3)
Add (2) and (3) term by term
- 10m = - 17.5 ( divide both sides by - 10 )
m = 1.75
Substitute m = 1.75 into either of the 2 equations
Using (1)
5p + 12.25 = 16 ( subtract 12.25 from both sides )
5p = 3.75 ( divide both sides by 5 )
p = 0.75
The cost of 1 peach = $0.75 and 1 mango = $1.75
