if the farmers market sold 35% of it produce and has 280 peaches remaining, how many peaches did it originally have on hand.
jonny [76]

Divide the amount left by the percentage left:

they sold 35%, so there is 65% remaining.

280 / 0.65 = 430.769

Round to 431

Now check:

431 x 0.35 = 150.85

Round to 151

431 - 151 = 280 left.

They originally had 431 peaches.
