how much money does james have to spend on toy cars?

Question

james currently has enough money to buy 45 toy cars. If the cost of each car was 10 cents less, could buy 5 more cars. how much money does james have to spend on toy cars?

Answer 1

let x be the price of the toy car:

 

45x = (x - .1)50

 

45x = 50x - 5

 

50x  - 45x = 5

 

5x = 5

 

x = 1

 

so, the price of a toy car is $1.00
