Using simple interest, it is found that $13,872 was loaned at 9%.
<h3>Simple Interest</h3>The amount of money after t years in simple interest is modeled by:
In which:
- P is the initial amount.
- r is the interest rate, as a decimal.
The interest earned is:
A bank loaned out $14000, in two parts, hence:
Part of it at the rate of 9% per year and the rest at 17% per year, hence:
The interest received in one year totaled $2000, hence:
Then:
Isolating as a function of
, then we can replace on the equation for the first interest.
Then:
$13,872 was loaned at 9%.

Answer:
Step-by-step explanation:
Ok, so break this down into each line and Graph
1) pages on the y and days on the bottom (x)
a) begins at origin, passing through the point (20,200)
200 - 0 / 20 - 0 = 200/20 = 10
therefore this line has a slope of 10
y = 10x
b) begins at (0,40) [also known as y-intercept], passes through (20,200)
200 - 40/20-0 = 160/20 = 8
Slope = 8
y = 8x +40
Graph is shown at bottom
Repeat the process for the rest
Break it down like this
2) A graph with days on the x axis and number of pages on the y axis.
There are two lines.
One line begins at (0,280) and passes through the point (20,80)
The other line begins at (0,240) and passes through the point (20,80)
80 - 280/ 20 - 0 = Slope 1
80 - 240/ 20 - 0 = Slope 2
(0, #) = y-intercept = #
3) A graph with days on the x axis and number of pages on the y axis.
There are two lines.
One line begins at the origin and passes through the point (25,200).
The other line begins at (5,0) and passes through the point (25,200).
200 - 0/25 - 0 = Slope 1
200 - 0 / 25 - 5 = Slope 2
(0, #) = y-intercept = #
4) A graph with days on the x axis and number of pages on the y axis.
There are two lines.
One line begins at the origin and passes through the point (7,56).
The other line begins at (0,40) and passes through the point (7,56)
56-0/ 7-0 = Slope 1
56-40 / 7-0 = Slope 2
(0, #) = y-intercept = #
