Question

A store sells 2 1/4 pounds of mulch for every 1 1/2 pounds of gravel sold. The store sells 180 pounds of mulch and gravel combined. How many pounds of each item did the store sell?

Answer 1

The pound of mulch sold is 108 and the pound of gravel sold is 72 pounds.

The pound of mulch sold will be:

= 2.25/(2.25 + 1.5) × 180

= 2.25/3.75 × 180

= 108

The pound of gravel sold will be:

= 1.5/3.75 × 180

= 72
