Question

The cost of two toy cars and a toy bus is $47. Four times the cost of the toy bus is 28 more than eight times the cost of the toy car. Find the cost of a toy car.

Answer 1

Answer:

Let the cost of a toy car be x.

Then the cost of two toy cars will be 2x

And the cost of a toy bus will be 47 - 2x

According to the given coondition,

4(47 - 2x) = 8x + 28

188 - 8x = 8x + 28

188 - 28 = 8x + 8x

16x = 160

x = 160/16

x = 10

The cost of a toy car = x = $10
