A car rental company charges a one-time application fee of 20 dollars, 45 dollars per day, and 15 cents per mile for its cars. W
crimeas [40]

Answer:

C(d,m) = 20 + 45d + 0.15m

Step-by-step explanation:

In this problem, we have that the cost of renting a car C is a function of the number of days d, and the number of miles driven, m.

There is also a fixed cost F.

So the equation for the cost of renting a car is:

C(d,m) = F + a*d + b*m

In which a is the daily cost and b is the cost per mile.

A car rental company charges a one-time application fee of 20 dollars, 45 dollars per day, and 15 cents per mile for its cars.

This means that F = 20, a = 45, b = 0.15

Write a formula for the cost, C, of renting a car as a function of the number of days, d, and the number of miles driven, m.

C(d,m) = 20 + 45d + 0.15m

there are 100 pennies in a dollar what fraction of a dollar 61 pennies right as a fraction as a decimal
Assoli18 [71]
So fraction is (parts)/(total)

percent means parts out of 100 so x percent=x%=x/100 so
61 out of 100=61/100=61%

if you simplify 61/100,
61/100=6.1/10 times 10/10=6.1/10 times 1=0.61/1 times 10/10=0.61/1 times 1=0.61


fraction=61/100
decimal=0.61
