How much (in dollars) will the seed cost? (Assume Bernice can only purchase full bags of seed.)

Question

Bernice wants to seed her large backyard with grass. Her backyard is in the shape of a rectangle with dimensions 120 feet by 80 feet. The seed costs $4.99 for a 1-pound bag, and each bag covers up to 1,050 square feet. How much (in dollars) will the seed cost? (Assume Bernice can only purchase full bags of seed.)

Answer 1

120x80 = 9600 square feet

9600/1050 = 960/105 = 192/21 =9.143 one pound bags

She'll have to buy 10 bags if they only come in 1 pound bags

10 x$4.99 = $49.90 for 10 bags

Answer 2

A = (120)(80)

A = 9600

9600 / 1050 = 9.14

Bernice needs to buy 10 bags.

What is the cost?
