Answer:
a. $60
Step-by-step explanation:
We will use simple interest formula to solve our given problem.
, where
A= Amount after t years.
P= Principal amount.
r= Interest rate in decimal form.
t= Time in years.
Let us find amount of loans repayable after 12 months for taking two amounts of $2000 and $1000.
As $2000 and $1000 are less than 2500, so the rate of loan will be 10%.

12 months = 1 year.




Now let us find amount repayable after 12 months for borrowing $1000.




Adding these amounts we will get total repayable amount after 12 months for borrowing $2000 and $1000 separately.

Now let us find repayable amount after 12 months for taking 1 loan. As $3000 is between $2501 and $7500, so rate of loan will be 8%.





Now let us find difference between both repayable loan amounts.


Therefore, the customer should have saved $60, if he had taken out one loan for $3000 and option a is the correct choice.
I hope this helps....
let one kg of potatoes be x
let one kg of carrots be y
8x + 5y = 28
(4) 2x + 3y = 11.2 (4)
8x + 12y = 44.8
7y = 16.8
y=2.4
x=2
