Can someone me with questions 11 and 12v? ?

11) you substitute the number of hours, h, in the equation they gave you to get the cost, c, she the painter makes

C=15h+245
C= 15(30.25)+245
C= 453.75+245
C= 698.75

12) p=45h
I got this answer because she earns 45 dollars an hour and this determines how much she gets paid depending on how many hours she works.

No he does not because he can only cover 12 square feet from 15 square feet which he will still need 3 more. this is because if 3×5=15 square feet and 15-12=3 which thats the answer
