Ginger earns $18,500 annually and has 22% of her gross earnings
withheld. What is the net amount of her paycheck each pay period if
she is paid biweekly?
2)Zack deposited $1,200 in a savings account that paid 7.75% simple
interest. What was the balance in his account at the beginning of the
third year?
3)Adam borrowed $1,200 for 18 months at 11.5% simple interest under an
addon plan. What was his monthly payment?

1)
18,500 * 0.22 = 4,070
18,500  4,070 = 14,430
14,430 / 26 = ?
2)
1,200 * 0.075 = x
3x + 1,200 = ?
3)
What do you think? 
for the secound question i did the same but the answer was wronn??
its
1,200 * 0.075 = x
3x + 1,200 =
i had 1470
1200*0.075=90
3*90+ 1200=1470 
I get the same answer, $1470, for the second problem.

i had a small test and i put that down and than on my test it said its wrong i don't know y?so i wanted to see if i did something wrong.
