We have been given that Willy has compounded monthly to invest his summer earnings of $4259 in the Rock Solid Bank. The bank is offering 6%. We are asked to find the amount of money will be after 5 years.
We will use compound interest formula to solve our given problem.
, where,
A = Final amount after t years,
P = Principal amount,
r = Annual interest rate in decimal form,
n = Number of times interest is compounded per year.
t = Time in years.
Since interest is compounded monthly, so 
and 
.
Therefore, Will will have approximately 
in 5 years.
Martha's total earnings is the sum of her fixed pay pay day and the extra she gains based on the number of toys she sold. Her total earnings may be expressed as,
44 + 2n
Since she desires to earn $80 or more, the inequality is expressed as
44 + 2n ≥ 80
Solving for n from the inequality,
n ≥18
Thus, the answer is the first choice.
The answer is x = 10, and it could alternatively be x = -10 depending on what topic this is and if negatives apply.
x^2 - 1 = 99
Add 1 to both sides.
x^2 = 100
Square root both sides
x = 10
