Question

Write an equation of variation to represent the situation and solve for the indicated information Wei received $55.35 in interest on the $1230 in her credit union account. If the interestvaries directly with the amount deposited, how much would Wei receive for the sameamount of time if she had $2000 in the account?

Answer 1

`\begin{gathered} \text{Wei recieved \$55.35 as interest for t years} \\ I=(P* R* t)/(100) \\ 55.35=(1230* R* t)/(100) \\ Rt=4.5 \\ \text{Now,} \\ I=(2000* Rt)/(100) \\ I=(2000*4.5)/(100) \\ I=\text{ \$90 (That much amount will be recieved by the Wei)} \end{gathered}`
