Answer:
a) t = 7x + 15
b) Nicole is paid $50 for 5 hours.
Step-by-step explanation:
flat fee = a price that will not change = $15
$7 per hour = a price of $7 for an unknown amount of hours (x) = 7x
Let "x" = amount of hours.
Let "t" = total cost.
Set the equation:
t = 7x + 15
Nicole babysits for 5 hours. Plug in 5 for x in the equation:
t = 7x + 15
t = 7(5) + 15
t = 35 + 15
t = 50
Nicole is paid $50 for 5 hours.
