Answer:
Enterprise charges more for a 6 day rental. ($284 for Hertz and $294 for Enterprise). Avery would save $4 if he rented with Hertz for 4 days.
Step-by-step explanation:
H = Hertz
E = Enterprise
x = Days rented
T = Total cost for x days, in $
<u>Hertz:</u> TH = 42x + 32
<u>Enterprise: </u> TE= 45x + 24
====================
6 Day Rental:
TH = 42*(6) + 32, = $284
TE = 45*(6) + 24 = $294
4 Day Rental:
TH = 42*(4) + 32, = $200
TE = 45*(4) + 24 = $204

Answer:
[50, 410]
Step-by-step explanation:
If the plumber works 0 hours, he still charges $50, so that is the minimum of the range of charges.
If the plumber works 8 hours, his hourly charge of 8×$45 = $360 is added to his fixed charge of $50 for a total of $410. That is the maximum of the range of daily charges.
The range of the function is $50 to $410.
