Answer:
1) (D)
2) (B)
3) (C)
Step-by-step explanation:
1) Amount borrowed = $1380 (P)
APR =13% or 0.13 (R)
Time = 15 months (T) = 15/12
Interest amount =
=
= $224.25
Total amount = 1380+224.25
= $1604.25
Monthly payment = 1604.25/15 = $106.95 (D)
2) Amount borrowed = $2240
APR = 15% or 0.15
Time = 18 months
Interest =
=
= $504 (B)
3) Amount borrowed = $5500
APR = 11.5% or 0.115
Time = 5 years
n= 12 (compounded monthly)
M =
=
= $120.95 (C)
Answer:
NOT the graph A and the graph B.
Step-by-step explanation:
y = mx + b
m - slope
b - y-integer
If m > 0 then the function is increasing.
if m < 0 then the function is decreasing.
We have y = -2x + 3
m = -2 < 0 the function is decreasing
b = 3 y-intercept = 3
The x-intercept: y = 0. Substitute
0 = -2x + 3 add 2x to both sides
2x = 3 divide both sides by 2
x = 1.5
Therefore your answer is C or D (look at the picture)
