Question

Aidan has $65 in his bank account. His brother Michael also has a bank account. They want to calculate the amount of money in both accounts combined. What variable is needed to calculate their combined total?

Answer 1

well, if you want to know how much money is in *both* accounts, you'll need to know *both* balances.

which person's balance is still not given in the problem?

Answer 2

Michael's isn't

Answer 3

good, so the variable still needed = Michael's balance
