You have to make the percent a decimal by moving the decimal to the left twice. then you need to multiply the other number.
This is the way to solve the problem
Multiply 12 by 37%.
12 × 0.37 = 4.44
B) at least 4
It could also be c... 4.44 is less than 8. But B is the closest answer to 4.44.
7844=7400(1+(8/12)r)
Solve for r
R=0.09*100=9%
