The regular price is 3.18.
50% off half the price, so you can either divide the regular price by 2 or multiply it by 0.50
3.18 / 2 = 1.59 ( 3.18 *0.50 = 1.59)
so the sale price is 1.59
now subtract the sale price from $5 to find the amount of change they got back:
5.00 - 1.59 = $3.14 change back
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.
