Sita and simran wanted to go for a vacation with their families and booked two cars
individually in zoomcar. com. the rent for the car for 12 hours is fixed and above that, additional
amount will be collected for every hour. sita paid rs.4600 for 17 hours, while simran paid, rs.
3800 for 13 hours. calculate the fixed charge and extra charge per hour.

Good morning,☕️

Step-by-step explanation:

Let x represent the fixed charge

and y represent the extra charge per hour

then we have to solve the following equations  system :

x + (17-12)y = 4600

x + (13-12)y = 3800

⇔

x + 5y = 4600 (1)

x +   y = 3800 (2)

(1)-(2)⇒ 4y = 4600-3800=800 then 4y=800 then y=200

we replace y by 200 in equation (2) : x = 3800-200 = 3600.

12cm

the answer is d

d. $180

step-by-step explanation:

if the dimensions of the room is 9ft by 12 ft, we have the area of the floor as,

so the area of the floor is 108 square feet, converting that into square yards we get,

the cost of carpet is $15 per square yard, therefore the cost of carpet for 12 square yards is,

hence, the cost of carpet is $180.

assuming the dimensions of the room be,

15 ft by 12 ft

so, the area of the floor of that room is,

we can convert 180 square feet into square yards, we know that,

1 sq ft = 0.111 sq yard

so, 180 square feet is,

so the area of floor is 20 square yards.

now, the cost of carpet is 15 dollars per square yard, therefore the cost of carpet for 20 square yards is,

so, it will cost $300.
