Abraham is buying some toiletries and creates a budget of $60 for his shopping. He buys 4 shower gels for $4 each, a tube of toothpaste for $3, and a box of laundry detergent. If he has $30 remaining in his budget, how much money, in dollars, did Abraham spend on the box of laundry detergent?
Let's be accurate as possible. Think before you answer.

Shower gel costs Abraham 4 shower gels * $4 = $16.

So the shower gel and toothpaste combined have cost him $16 + $3 = $19.

He had money remaining in his budget so the total cost of his shopping must have been $60 – $30 = $30.

The box of laundry detergent therefore cost him $30 – $19 = $11.

The answer: 11
