How to solve it to put 65% of his Christmas money in the bank.If he had $70 left after he put the money in the bank. How much money did he get for Christmas?

Pls help

Answer 1

$200

Explanation:

Let X be the amount of Christmas money he had at the beginning.

He put 65% of X in the bank. This is 0.65x

He has $70 left which is equal to 0.35x

We need to write an equation to find the value of x.

70 = 0.35x

Divide by 0.35 to find the value of x.

70/0.35 = 0.35x/0.35

200 = x

He received $200 for Christmas.
