Answer:
14.50x > 85
Step-by-step explanation:
divide both sides by 14.5
x>85/14.5 = 5.86 hours
x has to be greater than 5.86 hours
A
Antonia: 150 x 12 + 4,500 = 6,300
Cal: 250 x 12 + 3,400 = 6,400
Solving
2x + 6 = 4x - 4
Bringing like terms on one side
6 + 4 = 4x - 2x
10 = 2x
10 / 2 = x
5 = x
4.50x=y
