Okay so first figure out what 2.4 times 10 with the power of negative 3 is.
2.4 times 10 is 24 and 24 to the power of 3 is 13,824
so an addition problem could be 5,986+7,838= 13,824
then you could do for a subtraction problem 23,789- 9,965 = 13,824
I hope this helped you. (;

Answer:
Step-by-step explanation:
Since interest is compounded semi-annually (half a year or 6 months), in a spawn of 2 years, the interest will have been compounded 4 times. As given in the problem, each time the interest is compounded, the new balance will be 107% or 1.07 times the amount of the old balance.
Therefore, we can set up the following equation to find the new balance after 2 years:
