7.5% of what number is equal to 85% of 200?

85 % of 200 = 0.85 (200) = 170

7.5 % of x = 85 % of 200

7.5 % of x = 170

Cross multiply

7.5 (x) = 170(100)

7.5(x) = 17,000

To find the value of x, divide both side by 7.5

x= 17,000/7.5

x = 2266.66

7.5% of 2266.66 is equal to 85% of 200

she played for 18.75 hours.

step-by-step explanation:

if she played 2/4 of a hour on tuesday. and there is 60 minutes in an hour and 60 divided by 4 is 7.5. and she played 2/4 of an hour on thursday then again 60 divided by 4 is 7.5, you add 7.5+7.5=56.25. now you have to do 1/4 of an hour, it equals 3.75. now you have to add them all up. 3.75+7.5+7.5=18.75
