A. Two local supermarkets sell watermelons grown at McDowell's

farm. But Biggy Market sells their watermelons for $3.99 each,

regardless of size, whereas Harmless Trail Market sells their

watermelons for $0.19 per pound. For what weight will a

watermelon at Harmless Trail cost the same as any watermelon at

Biggy? If the largest watermelon grown at McDowell's farm

weighs 18 pounds, at which place should you buy your

watermelons?

For the watermelon at Harmless to cost the same as any watermelon at Biggy, the watermelon needs to be 21 pounds.

You should buy your watermelon at Harmless.

Step-by-step explanation:

1. So in order to figure out the number of pounds, you need to divide 3.99 by 0.19 which should give u 21 pounds.

2. So in order to figure out where u should buy the watermelon from, u have to do 18 pounds times $0.19 which should give u $3.42 at Harmless while at Biggy it would cost $3.99
