Answer: his weekly earnings
Step-by-step explanation:
He earns $(6.25 + 7.50) = $13.5 between the two jobs per hour
$13.5 = 1 hr
$x = 40hr
Cross multiply and make $x the subject,
x = $540 in 40 hours.
If he makes $540 in 40 hours,
18% of $540 =
18/100 = x/540
× = $97.2
George saves $97.2 from the two jobs weekly.
