Answer:
If I did my math correctly, They washed 15 cars on Sunday.
Step-by-step explanation:
50 cars = 100%
Therefore 1 car would be 2% because 50 is half of 100.
So because 30% would be 2 times the amount of cars, we divide 30 by 2, giving us 30% = <u>15 cars on Sunday</u>
With this information, we can take away 15 from 50 giving us 35 cars which is equal to 70% on Saturday
Here is some extra data:
10% = 5 cars
20% = 10 cars
30% = 15 cars
40% = 20 cars
50% = 25 cars
60% = 30 cars
70% = 35 cars
80% = 40 cars
90% = 45 cars
100% = 50%
Basically, every 10% is +5 cars

Answer:
She will be charged $180 once lets the account go past 6 months before making a payment.
Step-by-step explanation:
This is a simple interest problem.
The simple interest formula is given by:
![E = P*I*t](https://tex.z-dn.net/?f=E%20%3D%20P%2AI%2At)
In which E is the amount of interest earned, P is the principal(the initial amount of money), I is the interest rate(yearly, as a decimal) and t is the time.
After t years, the total amount of money is:
![T = E + P](https://tex.z-dn.net/?f=T%20%3D%20E%20%2B%20P)
In this question:
If she pays within 6 months, she is not charged any interest.
However, if after 6 months she has not paid the balance, she is charged 20% interest for this period.
Barbara financed a new bedroom set at the furniture store for $1,800.
This means that ![P = 1800](https://tex.z-dn.net/?f=P%20%3D%201800)
20 percent interest
This means that ![I = 0.2](https://tex.z-dn.net/?f=I%20%3D%200.2)
How much interest will she be charged once she lets the account go past 6 months?
6 months is half a year, so this is E when ![T = 0.5](https://tex.z-dn.net/?f=T%20%3D%200.5)
![E = P*I*t](https://tex.z-dn.net/?f=E%20%3D%20P%2AI%2At)
![E = 1800*0.2*0.5](https://tex.z-dn.net/?f=E%20%3D%201800%2A0.2%2A0.5)
![E = 180](https://tex.z-dn.net/?f=E%20%3D%20180)
She will be charged $180 once lets the account go past 6 months before making a payment.
