- 23. Multiple Choice
Matthew has a job where his daily pay P, in dollars, is given by the function P(h) = 15h, where h represents the number of hours worked that day. Last week, he worked two more hours on Tuesday than he did on Wednesday. If he worked c hours on Tuesday, which statements are true?
Select ALL that apply
P(c) represents Matthew's pay, in dollars, on Tuesday
15c represents Matthew's pay, in dollars, on Tuesday
P(c - 2) represents Matthew's pay, in dollars, on Wednesday
15c - 2 represents Matthew's pay, in dollars, on Wednesday
P(c) - P(c - 2) represents how much more Matthew's pay was on Tuesday than on Wednesday
