Bob earned $810 last summer. He spent $540. What percent of his earnings did he save?

Hey there!

Find the amount he saved by finding the difference between earnings and spendings.

810 - 540 = 270

Then, find the percent 270 is of 810.

Do this by dividing 270 by 810.

270 ÷ 810 = .3333

Multiply by 100 to get the percent.

.3333 × 100 = 33.33

He saved 33.33%.

Hope this helps!
