Question

Bob made $970 a week while Jim made $763 a week. How much more (in percentage) did Bob make more than Jim?

I know Bob made $207 more than Jim but i can't figure the percentage of how much more Bob made than Jim.

Answer 1

well
if we take Jim's pay as the 100%, that is, 763 is the 100%
then how much in percentage did Bob?
or
what is 207 in percent, from 763?

well \(\begin{array}{ccllll}
\$&\%
\\\hline\\
763&100\\
207&x
\end{array}\implies \cfrac{763}{207}=\cfrac{100}{x}\implies x=\cfrac{207\cdot 100}{763}\)
