Answer:
The percentage decrease = 18%.
Step-by-step explanation:
The formula used to find the percent change (increase or decrease) is:
x 100
Since the original amount of available credit is $750 and the new amount available is $615, we can use our formula above to calculate the percent decrease of available credit:
= .18 x 100 = 18%.
We translate Grayson's charges through the following mathematical expression : 35 h + 35 where h is the number of hours while that of Ian is 45h + 15. The number of hours where the charges are equal is 35h + 35 = 45h + 15; h = 2 hrs. Hence the number of hours minimum must be above 2 hours.
