In
may, liam and charlie had the same amount of money in their savings
accounts. in june, liam deposited $140 into his account. charlie said he
increased the money in his account by 5%. when they compared their
balances, they found that they were still equal.
how much money did they both have in their accounts in may?

Liam’s saving = x + $140
Charlie’s saving = x + 5%
In order to get the value of x, let’s find the amount which 5% is equals to 140
=> 2800
=> 5% = 0.05
=> 2800 x 0.05
=> 140
=> 2800 (amount that Liam and Charlie have in their account before they added)
Thus, Liam and Charlie both have $2800 on their account .
=> Liams = 2800 + 140 = 2940
=> Charlir = 2800 + 5% (140) = 2940.

Iam thinking the answer is a.) knew
