Since he hasn't read 70% of the book which is 35 pages, we need to know that 70% of what number is 35.

This is called a is over of, percent over 100 proportion.

If we place 70 over 100 and set that equal 35 over x we can cross multiply and divide to find the answer.

35 times 100 = 3,500

3,500 ÷ 70 = 50

Step-by-step explanation:

$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)
