Zack has two savings accounts with the total of $9,000. He withdew 10 percent from one and 60 percent from the other to buy his
klio [65]

The remaining balances in the first and second account are $5805 and $1020 respectively.

<em><u>Explanation</u></em>

Suppose, the initial balance in the first account was  x dollar.

As the total amount in two accounts was $9000, so the <u>initial balance in the second account was</u>  (9000-x) dollar

He withdrew 10% from the first and 60% from the second account to buy the ring which cost $2175. So, the equation will be......

0.10x+0.60(9000-x)=2175\\ \\ 0.10x+5400-0.60x=2175\\ \\ -0.50x= 2175-5400= -3225\\ \\ x=\frac{-3225}{-0.50}= 6450

So, <u>the initial balance</u> in the first account was $6450 and in the second account was ($9000 - $6450)= $2550

Thus, the remaining balance in the first account = 90% of $6450 = (0.90*6450)= \$5805

and the remaining balance in the second account = 40% of $2550 = (0.40*2550)=\$1020
