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?

69 pounds of peaches what you do is take 337.50 - 165 then you divide that by 2.50 and that gives you 69 pounds

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.
