solve and check your steps

1. Eric put 12% of his monthly paycheck in an IRA.  If he invests $72 in his his IRA, how much was his paycheck?

2. Of 32 students in a class, 28 passed.  what percentage of the students passed?

3. What amount of interest will you pay on a $8200 loan for 1 year if the interest rate is 15%?

4. convert 9/16 to percent
__________________________________________________________________________

1) .12x=72

   .12x/.12 = 72/.12
    x= 600
His paycheck is $600.

2)(28/32)* 100 =x

 .875 *100 =x
87.5=x

87.5% of the students passed.

3)
8200 * .15 = 1230
The amount of interest you will pay is $1230.

4)9/16=x/100

Cross multiply.
9(100)=16x

900=16x

900/16=x

56.25=x

56.25% is the answer.

Hope this helps.
