There are 24 students in room F1. 10 of them are boys. What percent of the students are girls?

58.33%

Step-by-step explanation:

10/24 × 100 gives a 41.67% of boys

If 41.67% are boys and the rest are girls, subtract from 41.67% from 100% to give 58.33%

58.33% are girls

$53.50

step-by-step explanation:

you have to subtract the amount of money chuck earned ($72.50) by the cost of the gas for the mower ($11.25) and the new string for the trimmer he bought ($7.75).

72.50-11.25=61.25

and then subtract $61.25 by the second thing he bought (the new string for the trimmer)

61.25-7.75=53.5

so in total it's $53.50 (53 dollars and 50 cents)
