$14.29 %$ $14.29%$

First find the amount by which the money increased.

The question implies that there was an increase FROM #3.50 TO $4.00.

The change is the difference, = $0.50.

This change is expressed as a fraction of the ORIGINAL value.

$$ \frac{0.50}{$} 3.50$ $$0.50/$3.50$

Convert to a percent. $\frac{$ 0.50}{$ 3.50} \times 100 %$ $($0.50)/($3.50)xx100%$

= $14.29 %$ $14.29%$

Use the formula:

Percent inc or dec = $\frac{change}{original} \times 100 %$ $"change"/"original" xx 100%$
