Answer:
$1,709.00
Step-by-step explanation:
First, let's convert the annualy interest rest (ia) to monthly(im):
(1 + im)¹² = 1 + ia
(1 + im)¹² = 1 + 0.04
(1 + im) =
im = 1.0033 - 1
im = 0.0033 = 0.33%
For an investiment, the final amount (A) can be calculated by:
Where R is the amount invested per month, i is the interest, and n the number of months
n = 40*12 = 480 months
2,000,000 = R*((1+0.0033)⁴⁸⁰ - 1)/0.0033)
2,000,000 = R*1,170.22
R = $1,709.00
here x intercept is -1, so coordinate would be (-1,0)
we use two points (2,7.5) and (-1,0) to find the slope
slope=-7.5/-3 = 2.5
now let us use slope m =2.5 and point (-1,0) to get the y intercept
y=mx+b
0=2.5(-1)+b
b=2.5
plugging value of m and b in slope intercept form to get the equation
y=2.5x+2.5
