One bag of ground bark will cover 160 square feet. Find how many bags should be purchased to cover a garden that is 10 feet by 45 feet.

Respuesta :

10 x 45 = 450, so we need to find how many bags of 160 square feet should be purchased to cover 450 square feet. The answer is at least 3 bags, because 160 x 3 = 480.
