during one month the orangevale parks and recreation district spent $5720 for various activities. they spent $1430 on mommy and
AysviL [449]

To solve this problem, we must figure out what percent of the total spending was spent on mommy and baby exercise programs. To figure this out, we should divide how much was spent on the mommy and baby exercise by the total amount spent on the district activities.

$1430/$5720 = 0.25

This is a percentage, or a portion out of 100, which means we must multiply this decimal by 100 to find its equivalent percentage.

0.25 * 100 = 25

Therefore, your answer is 25% of the total spending was spent on mommy and baby exercise programs.

Hope this helps!

If 9.54% of the battery life of each mobile phone is used in a day by a typical user, which mobile phone would use a total of 1.
Grace [21]
Sorry, I guess I was in a hurry. This is how I did it after carefully reading the problem. 
9.54% times which mobile phone (the one we are looking for=y) would use 1.908
that is: 0.0954 times y=1.908
0.0954y=1.908 dividing each side by 0.0954, we get y=20
So, the answer is y=20, or the mobile phone is 20
