You have 15 dollars and earn 50 more dollars doing chores. you then go to the store to buy a shirt for 10 dollars. how much money do you have left.

This is actually quite simple. Let's think about it!

You start off with $15 and then, you earn another $50 because you did all of your chores. Since you gained $50, that would mean that you have to add $50 onto your $15.

$15 + $50 = $65

After you add, you will end up with $65. After you do you chores, you have to got to the store to buy a shirt that cost $10. Since you are spending money, that means you are decreasing in the amount of $$$ that you have, which means that you have to subtract. You have to take the $10 that you are spending and subtract it from the amount that have already, which is $65.

$65 - $10 = $55

Since you have successfully subtracted, you can see that you will end up with $55 in the end of your transaction.
