Question 3Mr. Winking is purchasing a car and needs to finance $24,000 from the bank with an annual percentage rate (APR) of
4.8%. He is financing it over 5 years and making monthly payments. What is the monthly payment?
$104.54
$378.21
$450.71
$1225.56

Answers

Answer:

The monthly payment, PMT = $450.71

Therefore the correct option is C.) $450.71

Step-by-step explanation:

i) Value of Loan, or Present value, PV = 24000

ii) Annual percentage rate , APR = 0.048

iii) number of periods, n = 12

iv) periodic interest, R = APR / n = 0.048 / 12 = 0.004

v) number of years, t = 5

v) Monthly Payment, PMT = $(PV* R)/(1 - (1 + R)^((-1* n * t))) = (24000 * 0.004)/(1 - ( 1 + 0.004)^(-60))$ = $450.71

In the cafeteria there are 7 teachers 48 girls and 45 boys What is the probability that a person chosen at random from the cafeteria is a boy

Answers

total peoples = 7 + 48+ 45 = 100
probability of boys = number of boys / total people
45/100 = 9/20

7+48+45
48+45=93
so 93% chance of a boy getting chosen

A garden box has a perimeter of 27 1/2 feet. If the length is 9 feet ,what is the area of the garden box?

Answers

Perimeter=2 * lenght + 2 * width.

Data:
Perimeter= 27 1/2 ft=27.5 ft
lenght=9 ft

1)we have to calculate the width.
27.5 ft=2(9 ft)+2 width
27.5 ft=18 ft + 2 width
2 width=27.5 ft-18 ft
2 width=9.5 ft
width=9.5/2=4.75 ft

2) we calculate the area
area of a rectangle=length x width
area of this rectangle=9 ft * 4.75 ft=42.75 ft²,

answer: the area of the garden is 42.75 ft² (=42 3/4 ft²).

perimiter=2(L+W)
27 and 1/2=P=27.5
L=9
27.5=2(9+W)
divide bot hsids by 2
13.75=9+w
minus 9
4.75=W

area=LW
area=9*4.75
area=42.75
ara=42 and 3/4 feet^2
