Question

Lan spent 1/3 of his weekly allowance to buy some candy. To earn

more money, his parents let him wash the car for $10. What is his weekly
allowance if he ended with $15? Write an equation and solve.
O 1/3x-10 = 15 ; x = 75
O 1/3x + 10 = 15; x = 5
O 1/3x + 10 = 15; x = 15
O 1/3x - 10 = 15; x = 25

Answer 1

The correct equation to solve the problem is: 1/3x + 10 = 15, where x is the weekly allowance.

By solving the equation we get:

1/3x = 5

x = 15

Therefore, the answer is option C: 1/3x + 10 = 15; x = 15.

Lan's weekly allowance is $15.
