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

Answer 1

Let the amount be x
Money in savings of them =210
Money added = 15%
= 15/100*210
= 7/50
= 0.14

Answer 2

Answer:

$1400

Step-by-step explanation:

Let the initial balance of the accounts of Isaiah and Freddie be x

In April, Isaiah deposited $210 into his account.

So, Balance becomes x+210

Freddie increased the money in his account by 15%.

15%. When they compared their balances, they found that they were still equal.

So, This means 15% increment = 210

So, $15\% \times x = 210$

$\frac{15}{100}x = 210$

$x = \frac{210 \times 100}{15}$

$x = 1400$

So,the initial balance of the accounts of Isaiah and Freddie is $1400

Hence they both have $1400 in their accounts in March.
