I just started the 5th grade and I don't understand one of my math problems.
The problem is Mr. Smith bought 2 similar T-shirts and a belt. He paid $100 to the cashier and received $13 in change. Find the cost of each T-shirt. (shouldn't the price of the belt be in the question?)
Ok, thank you. I will ask my teacher tomorrow if he left part of the question out.
The price of the belt was definitely omitted from the question, because with it being unknown, you cannot figure the price of the shirts.

Yes I agree this is a hard question and the belt should be added in
To solve this math problem, we need to set up an equation and use basic algebra to find the cost of each T-shirt. Let's break down the problem step by step:
1. Identify the given information: Mr. Smith bought 2 similar T-shirts and a belt, paying $100 to the cashier and receiving $13 in change.
2. Let's assume the cost of each T-shirt is 'x' dollars. Since the two T-shirts are similar, they have the same price.
3. The equation can be set up as follows: 2x (cost of 2 T-shirts) + cost of belt = total amount paid. In this case, it will be 2x + cost of belt = $100.
4. Since the problem states that Mr. Smith received $13 in change, we know that the $13 is the difference between what he paid and the total cost. So we have: $100 - $13 = $87. This represents the total cost of the 2 T-shirts and the belt.
5. We can now rewrite the equation as: 2x + cost of belt = $87.
6. However, since the problem only asks for the cost of each T-shirt, we can disregard the cost of the belt and modify the equation as: 2x = $87.
7. To find the cost of each T-shirt, we need to isolate 'x' by dividing both sides of the equation by 2: 2x/2 = $87/2.
8. Simplifying, we have: x = $43.50.
Therefore, each T-shirt costs $43.50.
