Diyoshana, Hemant and Rupesh got different answers for this problem: {-10-3(10÷2)}-4. Diyoshana's answer was 1, Hemant's answer was -29, and Rupesh's answer was 21

a). Which student had the correct answer?
b). Show and explain how other two students got their answers. What errors did they make?

My opinion on this:
this is a way to long question

I'm giving 20 points for this​

a)hemant is correct

b) they didn't solve this according to BoDMAS so they got wrong answer

the answer is 200

step-by-step explanation:

the way the question is worded, it seems to imply the $264 interest is simple interest, not compound interest.

the simple interest for 2 years is $264; the simple interest for 1 year is $132.

$132 interest on a $600 investment means an interest rate of (132/600)*100 = 22%.

the value of $200 at 22% interest compounded annually for three years is

200%281.22%29%5e3

the amount of interest is that value, minus the original $200.

a is the right answer
