Question

6) Tanecia borrowed $15 from her parents to buy a ticket to see her favorite band. Her neighbors gave her $5 for mowing the lawn, which she gave back to her parents. How much money did she owe them now?

Answer 1

Ok, let's first think about the situation like it was our situation.

your parents borrowed you $15

you gain $5 mowing the lawn , so you give them this $5.

What operation should we do? we shoud "remove" this quantity from the debt, so the operation needed is substraction

15-5=10

So Tanecia owe them parents now only 10 dollars.
