A rental car agency charges $25.00 per day and 28 cents per mile. (a) Calculate the rental charge if you rent a car for 5 days and drive 200 miles. (Round your answer to the nearest cent.) $181 Correct: Your answer is correct. (b) Use a formula to express the cost of renting a car as a function of the number of days you keep it and the number of miles you drive. (Let d be the number of days you rent the car, m the number of miles you drive the car, and C the cost in dollars of renting the car.) C(d, m)

a) $181

b) C(d, m) = 25d + 0.28m

Step-by-step explanation:

Car charges = $25 per day

Car charges per mile = 28 cents = $28/100 = $ 0.28

a)

Rental charges for 5vdays and 200 miles

= 25*5 + 0.28*200

= 125 + 56

=$181

b)

Let d be the number of days you rent the car, m the number of miles you drive the car, and C the cost in dollars of renting the car.) C(d, m). Therefore,

C(d, m) = 25d + 0.28m

step-by-step explanation:

given perimeter: 28cm

length: 9cm

atp,

2(l+w)=p of the reactangle

2(9+x)=28

18+2x=28

2x=28-18

x=10/2

x=5

therefore width is 5 cm
