Doug made a 3 year investment. The interest rate was 4.5%. After 3 years, he earned $675 in interest. how much was the original investment? A. 2,000
B. 4,000
C. 5000
D. 3,000

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

step-by-step explanation:

total income = price of one ticket   *   number of tickets sold

  y                 =     4                                   x

so the equation is y=4x     with x≥0   because number of tickets sold can not be negative

thus the equation is a semi -line with an end point at

(0,0)

passing through :

x=1     y=4(1) = 4   so through (1,4)

discount price = (original price)(1 – 0.15)

is the right answer   on edge
