Charles will babysit for up to 4 hours and charges $7 per hour. write a function in function notation for this situation.

X hour and 7 dollars per hour

x = hour

7(x) is your function

thank you for Anlian for pointing it out.. there is 4 hours

so x = 4

plug in 4 in x. 7(4)

7 x 4 = 28

28 is your answer

hope this helps
