Question 174115
let the cost of sweet potatoes,apples,and onions be p,a and n respectively
:
9p=6a...eq 1
p=2n....eq 2
a=n+24..eq 3
:
take values of p and a from eq 2 and 3 and plug them into eq 1
:
9(2n)=6(n+24)
:
18n=6n+144
:
12n=144
:
cost{{{highlight(n=12)}}}per pound of onions
:
cost{{{highlight(p=2n=2(12)=24)}}}per pound of s. potatoes
:
cost{{{highlight(a=n+24=12+24=36)}}}per pound of apples
