Question

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

Answer 1

Well it actually you can tell the answer, the answer will be 4x7=28
If you mean by another way then is: X/7less than or equal to 4
well then is 7x=?

Answer 2

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
