Question

Three friends rented a car for a week and divided the cost equally. What was the total cost of renting the car ?

Answer 1

Answer:

The cost would be $ 180.

Step-by-step explanation:

(1) Let x be the cost( in dollars ) for one week if three friends are kept in the car,

Since,

two-week rate = 1.5 × one week rate.

Thus, data is insufficient to find the total cost of renting the car,

(2) Since, total cost = x,

If number of friends = 3,

Then the cost paid by each friend = $\frac{x}{3}$ dollars,

If number of friends = 4,

Then the cost paid by each friend = $\frac{x}{4}$ dollars,

According to the statement (2),

$\frac{x}{3}-\frac{x}{4}=15$

$\frac{4x-3x}{12}=15$

$\frac{x}{12}=15$

$\implies x = 12\times 15 = 180$

Hence, the total cost of renting the car would be $ 180.
