Answer:
1 Regroup terms.
x-3<-11x−3<−11
2 Add 33 to both sides.
x<-11+3x<−11+3
3 Simplify -11+3−11+3 to -8−8.
its x<−8
9. $112.50 / 9 lawns = $12.50 per lawn
10. $122.50 / 7 lawns = $17.50 per lawn
11. $112.50 / 7.5 hours = $15.00 per hour
$122.50 / 5 hours = $24.50 per hour
Alastair earns more per hour
12. Taryn: 49 more hours ($735 / $15.00)
Alastaie: 30 more hours ($735 / $24.50)
You found how much money they charge per hour in 11 so use that to find how many hours it takes to earn $735.
