z = 8 + 6x - px Subtract 8 from both sides
z - 8 = 6x - px Factor the x out of 6x - px
z - 8 = x (6 - p) Divide both sides by (6 - p)
= x Switch the sides to make it easier to read
x = <span>

Price of DVD player ≥ $150
Saved = $80
Amount needed = $150 - $80 = $70
Saving per week = $10
Let x be the number of weeks needed:
80 + 10x ≥ 150
10x ≥ 150 - 80
10x ≥ 70
x ≥ 70 ÷ 10
x ≥ 7
Answer: She needs to save for for at least 7 weeks.
