Answer:
75% off
Step-by-step explanation:
I would personally say use a calculator, but whatever your instructor says.
First, do $600 off. You could also do 75% off first, but you choose. If you subtract $600 from $868, you get $268.
Next, do 75% off. If you take 100% - 75%, you get 25%, or 1/4. Multiply $868 by 1/4 and you get $217, which is the better deal.
So, to conclude, $217 is less than $268, and therefore 75% off is the better deal.
Answer:
You shoud invest $0.204, it is an small amount each month.
The formula to calculate the monthly saving is

with PP: periodic payments, A: amount desired, n: number of payments in one year, Y: number of years.
In this case A = 88, n= 12 (the payments are monthly), Y=18, APR=7%.
Replacing in the formula you obtain that 
Mrs. Cali's Lower Quartile:2
Mrs. Cali's Upper Quartile:4
Mr. Ronald's Lower Quartile:4
Mr. Ronald's Upper Quartile: 7
Lower Quartile 2<4 (Mr.Ronald's is greater)
Upper Quartile 4<7 (Mr.Ronald's is greater)
Mr. Ronald's Upper and Lower Quartiles are Greater than Mrs. Cali's Upper and Lower Quartiles.
Mr. Ronald's Lower Quartile:4
Mrs. Cali's Upper Quartile:4
D is correct because Mrs. Cali's upper Quartile is at 4, which is where Mr. Ronald's Lower Quartile is.
Hopefully that helps!
Good Job getting it right on your own!
