Answer 1

Answer: $88

Explanation:

1. Plug in the given data into the formula.

p = 80

r = 0.1 (represents 10%)

t = 1 year

2. Solve for i based on the formula's values

i = (80)(0.1)(1) = 8

Interest earned is $8 but THIS IS NOT THE FINAL ANSWER!

3. Add i (interest) to p (starting amount)

Elena started with $80, so the interest of $8 is added for a final answer of $88 after one year.

Answer 2

`~~~~~~ \textit{Simple Interest Earned} \\\\ I = Prt\qquad \begin{cases} I=\textit{interest earned}\\ P=\textit{original amount deposited}\dotfill & \$80\\ r=rate\to 10\%\to (10)/(100)\dotfill &0.10\\ t=years\dotfill &1 \end{cases} \\\\\\ I = (80)(0.10)(1) \implies I = 8\hspace{5em}\underset{ \textit{accumulated amount} }{\stackrel{ 80~~ + ~~8 }{\text{\LARGE 88}}}`
