Answer:

Step-by-step explanation:
Let x be the number of days you want to rent
The flat rate for car rental is $35 a day
As for insurance, $10 for 3 days or fewer, and $5 per day if more than 3 days that is

Combine this with the flat rental rate $35 a day and we have

The interest rate she would pay would be is $7,200
To find the answer you would multiply 1,300 by .06, which gives you a commission of $78.
Hope this helps!
Let us convert all figures into decimals so that we can compare them easily.
Monday 0.3
Tuesday 15% = 0.15
Wednesday 1/6 = 0.1666
Thursday 0.2
Friday 1/8 = 0.125
Clearly, I spent the least amount of time on Friday using IT and the time is 0.125 or 1/8.
multiply the price by the discount then subtract the answer from the price
4 * 0.20 = 0.80
4-0.80 = 3.20
sale price is $3.20
