Kylie saved $550 from babysitting. she used 32% of her money for a down payment on summer camp and 3/20 of her savings for two new video games. she deposited the rest into a college savings account. expressed as a decimal, what part of her money did kylie deposit into her college savings account?

%53

Step-by-step explanation:

3/20=%15

15+32=%47 for both video games and camp

100-47= %53 left over for college

.53

Step-by-step explanation: Of Kylies $550, 32% was for a down payment for summer camp. This is calculated with the formula 550 x .32 = $176 down payment.

She used 3/20 for two video games. 3/20 = .15, so the video games cost .15 x $550 = $82.50.

Kylie spent $176 + $82.50 = $258.50.

$550 savings - $258.50 = $291.50 is the amount that she put into her savings account. Expressed as as decimal, it is 291.50/550 = .53, so she put .53 of her babysitting money into her college savings account.
