Answer:
Step-by-step explanation:
We would apply the formula for determining simple interest which is
expressed as
I = PRT/100
Where
P represents the principal
R represents interest rate
T represents time in years
I = interest after t years
From the information given
T = 5 years
P = $15,575
R = 21%
Therefore
I = (15575 × 21 × 5)/100
I = 16353.75
Interest paid is $16353.75
Total amount that Sam would have paid for the car would be
16353.75 + 15575. = $31928.75
Answer:
Step-by-step explanation:
30 students volunteered to set up booths for the school fair. All of the students worked 2 hours after school on Thursday and on Friday. This means the total number of hour worked on Thursday is 30 × 2 = 60 hours and Friday is 30 × 2 = 60 hours
Twelve of them also worked 3 hours on Wednesday. It means that the total number of hour worked on Wednesday is
12 × 3 = 36 hours
If they did this for 2 weeks, it means that they worked for 2 Wednesdays, 2 Thursdays and 2 Fridays.
Total number of hours worked will be
2×60 + 2×60 + 2×36 = 120 + 120 + 72 = 312 hours
Answer:
Step-by-step explanation:
y - y1 = m(x - x1)
slope m = 3/2, y1 = -7, x1 = 4
y + 7 = 3/2(x - 4)
y + 7 = 3x/2 - 6
y = 3x/2 - 6 - 7
y = 3x/2 - 13
1 hour and 1/4 is a 75 percent difference between longest and shortest time a customer waited
