Question

Please help I’m confused

Answer 1

now, we're assuming is simple interest, so

`~~~~~~ \stackrel{\textit{\LARGE Account 1}}{\textit{Simple Interest Earned}} \\\\ I = Prt\qquad \begin{cases} I=\textit{interest earned}\\ P=\textit{original amount deposited}\dotfill & \$3000\\ r=rate\to 7\%\to (7)/(100)\dotfill &0.07\\ t=years\dotfill &3 \end{cases} \\\\\\ I = (3000)(0.07)(3) \implies I = 630 \\\\[-0.35em] ~\dotfill`

`~~~~~~ \stackrel{\textit{\LARGE Account 2}}{\textit{Simple Interest Earned}} \\\\ I = Prt\qquad \begin{cases} I=\textit{interest earned}\\ P=\textit{original amount deposited}\dotfill & \$10000\\ r=rate\to 6.5\%\to (6.5)/(100)\dotfill &0.065\\ t=years\dotfill &2 \end{cases} \\\\\\ I = (10000)(0.065)(2) \implies I = 1300`
