Question

the total cost c a painter charges to paint a house depends on the number h of hours its takes to paint the house. this situation can be represented by the function rule c= 15h + 245 . what is the cost if the painter works for 30.25 hours

Answer 1

given that

c = 15h + 245

when h = 30.35 , cost c = (15 × 30.35) + 245

= 453.75 + 245 = 698.75

so cost if painter works = 698.75 unit of currency.
