Answer:

n=7+2/3

usually garages charge for a whole day but in this case I don't exactly know if you would round up to 8 or not

Step-by-step explanation:

C(n) is just a stand-in for the total cost

since we know the total cost equals 115, we can plug it in for C(n)

115=40+15n

now all we need to do is solve

first we isolate the variable by subtracting 40 from both sides

115=40+15n

155=15n

now we just solve by dividing both sides by 15

155=15n

n=7+2/3

usually garages charge for a whole day but in this case I don't exactly know if you would round up to 8 or not

please give a thanks or brainliest if this was helpful :)
