# Lester worked 12 hours last week at the grocery store and and $93.00. If he continues to earn the same hourly pay, how many additional hours must he work to earn another$62.00?

The rate of his work = $earned/hours worked Therefore, last week he earned $\frac{93}{12}$We can simplify this to $\frac{31}{4}$Now we can set up a proportion. $\frac{31}{4} = \frac{62}{x}$Let $x$= hours he must work to earn$62. Note that on both sides, we have $earned/hours worked. We can cross multiply ($\frac{a}{b} = \frac{c}{d}$and $a d = c b$are equivalent) $31 x = 248$$x = 8\$
