Question

Mary has $10 in savings. She owes her parents $50. She does some chores and her parents pay her $12. She also gets $25 for her birthday from her grandmother. Does Mary have enough money to pay her parents what she owes them? If not, how much more does she need?

Answer 1

Mary dose not because 10+25+12= 47
so she would be 3 dollars off/she would need 3 dollars.

Answer 2

Mary owes 50$.
and has 10$ + 12$ +25$ in her pocket.
In total, that adds up to 47$, making her 3$ short to repay her parents.
