Question

At the end of the day, a fruit vendor counted and foutdoor she had 4/3 as many oranges as she had apples. She had 84 total apples and oranges .how many apples did she sell

Answer 1

x number of oranges
y number of apples
she had 4/3 as many oranges as she had apples
4/3x=y
x+y = 80
we solve the system
x+y = 80
4/3x-y=0
x+y = 80
4x-3y=0
7y=320=> y=45.7
and x=34.3
so we can assume that x=34 and y=46
