Shaun earns $73.20 in 6 hours at his weekend job.
$73.20%2F6=12.2 per hour
Jeff earns $55.50 in 5+hours.
$55.50%2F5=11.1 per hour
a)
Calculate their earning for five different lengths of time.
for 1 hour Shaun earns $12.2
for t hours Shaun earns $12.2%2At
if t=4, Shaun earns $12.2%2At=12.2%2A4=48.8
if t=5, Shaun earns $12.2%2At=12.2%2A5=61
if t=7, Shaun earns $12.2%2At=12.2%2A7=85.4
if t=8, Shaun earns $12.2%2At=12.2%2A8=97.6
if t=10, Shaun earns $12.2%2At=12.2%2A10=122

for 1 hour Jeff earns $11.1
for t hours Jeff earns $11.1%2At
if t=4, Jeff earns $11.1%2At=11.1%2A4=44.4
if t=5, Jeff earns $11.1%2At=11.1%2A5=55.5
if t=7, Jeff earns $11.1%2At=11.1%2A7=77.7
if t=8, Jeff earns $11.1%2At=11.1%2A8=88.8
if t=10, Jeff earns $11.1%2At=11.1%2A10=111
b)
Who makes more money after an 8-hour shift?
after an 8-hour shift Shaun earns $12.2%2At=12.2%2A8=97.6
after an 8-hour shift Jeff earns $11.1%2At=11.1%2A8=88.8
so, Shaun makes more money after an 8-hour shift
