Stumped : ( john earned some money mowing lawns. he bought a battery for 1.85$ and gave his mother 25$. he bought gas for 7.50$, and then spent half of the remaining money on clothes. if john has 40.25$ left, how much money did he earn mowing lawns?

John earned $114.85 from lawn mowing.

Step-by-step explanation:

John has 40.25$ left but he spent half of the remaining money on clothes before.

So he had 40.25*2 = 80.50 before.

He bought a battery for 1.85$ and gave his mother 25$. He bought gas for 7.50$.

So before he did all those things, he had 80.50+7.50+25+1.85 = $114.85

John earned $114.85 from lawn mowing.

18.8 cubic inches.

step-by-step explanation:

volume of a cone = πr²h

r = 1.5 inches

h = 8 inches

pi = 3.14

volume of our cone = × 3.14 × 1.5² × 8 = 18.84 square inches

or equals to 18.8 square inches rounded up to nearest tenth.
