at the grocery store avacados cost three times as much as grapes kiwis cost .75 less than avocados if i spent a total of 16.75 h
Romashka [77]
A - avocados, G - grapes, K - kiwis.
We know that: A = 3G, K = A - 0.75
So: G = A / 3
A + G + K = 16.75
A + A/3 + A - 0.75 = 16.75
7/3 A = 16.75 + 0.75
7/3 A = 17.50
A = 17.50 : 7/3
A = $7.50
G = 7.50 : 3 = $2.50
K = 7.50 - 0.75 = $6.75
Answer:
Prices of the fruits are A = $7.50, G = $2.50 and K = $6.75.
