Mo's farm stand sold a total of 165 pounds of apples and peaches. she sold apples for a $1.75 per pound and peaches for $2.50 per pound. if she made $337.50, how many pounds of peaches did she sell?

X=pounds of apples
y=pounds of peaches.
we suggest this equation:
x+y=165
1.75x+2.5y=337.5
We solve this equation by substitution method:
x=165-y
1.75(165-y)+2.5y=337.5
288.75-1.75y+2.5y=337.5
0.75y=337.5-288.75
0.75y=48.75
y=48.75/0.75=65

x=165-y
x=165-65=100.

She sell 100 pounds of apples and 65 pounds of peaches.
