Question

A 6-pound watermelon costs $2.40 before a 30% discount. Which equation would allow you to find the discounted price of the watermelon?

Answer 1

The unit price of watermelon is

$2.40
--------- = $0.40/lb.
6 lb

The discounted price of the watermelon would be (1.00-0.30)($0.40)

= 0.70($0.40) = $0.28/lb

Answer 2

That equation would look like this:

2.4 - 2.4 * .3 = p

p = price
