#1---> let the number you are trying to find be x for the following questions
30%*x=15
x=15/30%
x=50
#2
10%*x=14
x=14/10%
x=140
#3
(4/32)*100
is the same as (1/8)*100= 12.5%
#4
1%* x=11
x=11/1%
x=1100
by the way * means multiply
15000 * (1+ 0.03)^4
15000 *1.1255 = 16882.63 total after 4 years
16882.63 - 15000 = 1882.63 total interest
