the total cost c a painter charges to paint a house depends on the number h of hours it takes to paint the house. This situation can be represented by the function rule c=15h+245. What is the total cost if the painter works for 30.25 hours?
Answer
698.75
Explanation
The total cost is given by the function:
c = 15h+245
where h represent the number of hours.
When h = 30.25 hour, the cost will be;
c = 15h+245
= (15 × 30.25) + 245
= 453.75 + 245
= 698.75
