 Question from chelsey, a student: I am unsure on how to solve this problem, 600(1+0.05) 7 ?

Hi Chelsey,

Do you mean

$600 \left( 1+0.05 \right)^{7}?$

If so then $1 + 00.5 = 1.05$ and hence

$600 \left( 1+0.05 \right)^{7} = 600 \left( 1.05 \right)^{7}.$

Use your calculator to calculate

$\left( 1.05 \right)^7 = 1.05 \times 1.05 \times 1.05 \times 1.05 \times 1.05 \times 1.05 \times 1.05$

and then multiply the result by 600.

I hope this helps,
Penny
