Set up and solve a proportion for the following application problem. If 5 pounds of grass seed cover 394 square​ feet, how many pounds are needed for 7486 square​ feet?

Answer 1

Let x be the number of pounds needed for 7486 square feet.

The proportion can be set up as:

5 pounds / 394 square feet = x pounds / 7486 square feet

Cross multiplying, we get:

5 * 7486 = 394x
37430 = 394x

Divide both sides by 394 to solve for x:

x = 37430 / 394
x = 95

Therefore, 95 pounds of grass seed are needed for 7486 square feet.
