Question

Prompt

One gallon of sealant costs

$13

and will cover

300

square feet of a surface. A deck has a total surface area of

d

square feet. Which equation represents the cost

c

, in dollars, of the sealant needed to cover the deck twice?

c = \frac{300 d}{13}

c = \frac{600 d}{13}

c = 13 (\frac{d}{150})

c = 13 (\frac{d}{300})
