Solve:
the total cost (c) in dollars of parking in a garage for n days is given by
the function c(n) = 40 + 15n.
if the total cost was $115.00, for how many days was the car parked?

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 :)

the final price would be 29.6925

step-by-step explanation:

39.59 minus 25% equals 29.6925

percentage - 25%

probability - 0.25

we know,

total amount of students in class = 20

total boys = 10

total girls = 10

no of girls who wear glasses = 10/2 = 5

probability of choosing a girl with glasses is =

number of girls wearing glasses/total number of students in the class = 5/20

thus, percentage of selecting a girl wearing glasses will be

= 5/20 × 100

= 5 × 5

25%

therefore,

probability will be 0.25
