Use rounding or compatible numbers to estimate the difference 762-332

We have to use rounding or compatible numbers to estimate the difference of 762-332

Now rounding here can be done like rounding the tens place or the hundreds place and each will produce different result.

Rounding to tens place :

762=760

332=330

Difference =

Rounding to hundreds place :

762=800

332=300

Difference =

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.
