The model t=100+12 x represents the cost, in dollars of renting a car, where x is the number of days the car rented. What’s the total rental cost if one rents the car for 5 days.

t = 100 + 12(5)

To find the total rental cost if the car is rented for 5 days, we can substitute the value of x=5 into the given model t = 100 + 12x.

Plugging in x=5, we have:
t = 100 + 12(5)
= 100 + 60
= 160

Therefore, the total rental cost for renting the car for 5 days would be $160.
