Answer: . $50

Explanation:

The formula to find the compound amount (compounded quarterly) is given by :-


A=P(1+(r)/(4))^(4t), where P Is principal amount, r is the rate of interest in decimal and t is the time in years.

Given : Aaron puts $1,000 in an account that pays 10% interest compounded quarterly.

Then, P=1000, r=10%=0.1 ; t=
(6)/(12)=0.5 year

Now,
A=1000(1+(0.1)/(4))^(4(0.5))


A=1000(1.025)^(2)=1050.625

Then , Compound interest=
A-P=1050.625-1000=50.625\approx\$50

Hence, he earns the estimated interest of $50.
