In this question give all answers to two decimal places. Carlos decides to take out a loan of 20,000 Peruvian Soles (SOL) to buy a car. His bank offers two options to finance the loan. Option A: five year loan with an annual interest rate of 12.8% compounded quarterly. No deposit required.
Option B: five year loan with an annual interest rate of r% compounded monthly. Terms of the loan require a 10% deposit and monthly repayments of SOL 400.

first one because it can't have a fraction in it

step-by-step explanation:

unless you made a typo, the answers are both a and c.

step-by-step explanation:

1.5/3 is .5 whereas 3/9 is .3333333 not proportional

22/33 is .66666 and 4/6 is also .66666 proportional

2/4 is .5 whereas 142/213 is .66666 not proportional

14/7 is 2 and 7/3.5 is also 2 proportional

you could've also checked it by doing this simple division:

if the larger fraction divides with the smaller fraction to equal 1, it is proportional. so let me show you what i mean:

when i divide 22/33 by 4/6 i get 1, so we know it is proportional, and it is the same with 14/7 and 7/3.5. now if i divide 3/9 by 1.5/3 i get .66666 so therefore we know it is not proportional.

there are many ways to do this so i wanted to show you some possible ways.

10 - 8 = -2

  8 - 6 = -2

etc, so -2 is the common difference
