Question

Jenna can't wait to play in her new sandbox! Her mom fills the sandbox with seven 50-pound bags of sand. Then, Jenna uses her bucket to dump out sand 10 times. If she dumps out 8 ounces of sand each time, how many pounds of sand are left in the sandbox?

Answer 1

345 pounds

Explanation:

Each bucket dumps out 8 ounces of sand

8 ounces = 1/2 pound

So total sand dumped 10 times = 1/2 x 10 = 5 pounds

Originally sandbox had 7 x 50 = 350 pounds of sand

Sand left in box = 350 - 5 = 345 pounds
