Question

Help please. Thanks in advance.
In March, Isaiah and Freddie had the same amount of money in their savings accounts. In April, Isaiah deposited $210 into his account. Freddie increased the money in his account by 15%. When they compared their balances, they found that they were still equal.

How much money did they both have in their accounts in March?

Answer 3

r their answer choices?

Answer 4

Say their initial balance is \(x\)

If Isaiah deposits 210, then his amount is now \(x+210\)

If Freddie's account increased by 15% (i.e multiply by 1.15), then his account is at \(1.15x\)

So since these amounts are equal, you need to solve for \(x\) in the equation:
\[ x+210 = 1.15x\]

Answer 5

the correct answer is 1400

Answer 6

Yes, the correct answer is 1400. Nice job, @Annah.bee! :)
