$E = 9.5 h, $ 19.00$ $E=9.5h,$19.00$

Explanation:

$to calculate her earnings (E) per hour$ $"to calculate her earnings (E) per hour"$

$hourly rate = \frac{$ 28.50}{3} = $ 9.50$ $"hourly rate "=($28.50)/3=$9.50$

$\Rightarrow for 2 hours = 2 \times $ 9.50 = $ 19.00$ $rArr"for 2 hours "=2xx$9.50=$19.00$

$to establish an equation multiply hourly rate by h$ $"to establish an equation multiply hourly rate by h"$

$\Rightarrow $ E = 9.5 h$ $rArr$E=9.5h$

$check equation for 3 hours that is h = 3$ $"check equation for 3 hours that is h = 3"$

$E = 9.5 \times 3 = $ 28.50 \leftarrow True$ $E=9.5xx3=$28.50larr" True"$
