jose needs at least $95 to go on the class trip, he has saved $15 , he makes $20 for each lawn he mows . write an solved inequality to determine how many lawns jose needs to mow together .

Respuesta :

15 + 20x > = 95
20x > = 95 - 15
20x > = 80
x > = 80/20
x > = 4 <== so he needs to mow at least 4 more lawns
95 = 20x + 15
95 (-15) = 20x + 15 (-15)
80/20 = 20x/20
4 = x

Jose needs to mow 4 lawns

hope this helps
