Question

I need to use simple formula I = Prt and elementary algebra to find the missing quantities in this table.

Answer 1

Using the formula I = Prt with the given values of I, P and r, let's calculate the value of t.

We need to remember that the percentage value r = 6% is equivalent to r = 0.06.

So we have:

`\begin{gathered} I=P\cdot r\cdot t\\ \\ 3696=8800\cdot0.06\cdot t\\ \\ 3696=528\cdot t\\ \\ t=(3696)/(528)\\ \\ t=7 \end{gathered}`

Therefore the answer is t = 7 years.
