Margo borrows $200, agreeing to pay it back with 4% annual interest after 16 months. How much interest will she pay? Round your answer to the nearest cent, if necessary.

Interest I = $10.67

Step-by-step explanation:

Simple interest I = principal × rate × time

I = Prt

Given;

Principal P = $200

rate r = 4% = 0.04

time t = 16 months = 16/12 years

Substituting the given values;

I = $200 × 0.04 × 16/12

I = $10.66666666666

I = $10.67

She will pay $10.67 interest.

b

step-by-step explanation:

a difference is the result of subtraction. while each of these expressions has subtraction in it, a difference will be the result when subtraction is the last operation applied in the order of operations for the expression. this means subtraction must be outside of the parenthesis. only b has this.

what is the question? i am guessing you are looking for the area.

to find an area, you have to do length x width.

in this case, it would be 12 ft x 4 ft = 48 sq. ft
