His weekly allowance was $______

Answer :

Using equations, the weekly allowance was $14.40

What was his weekly allowance?

Let's denote Castel's weekly allowance as "A." According to the information given:

He spent half of his allowance playing mini-golf, which is A/2.

He earned $5.46 from cleaning gutters.

His ending balance is $12.66.

So, we can set up the equation:

A - (A/2) + 5.46 = 12.66

To solve for A:

A - A/2 + 5.46 = 12.66

(2A - A)/2 + 5.46 = 12.66

A/2 + 5.46 = 12.66

A/2 = 12.66 - 5.46

A/2 = 7.20

A = 2 * 7.20

A = 14.40

Castel's weekly allowance was $14.40.
