Question

An item is marked down 10% each week until it sells. If the item is priced at $150 what is the cost after 3 weeks? 6 weeks?

Answer 1

3 weeks- 112.95

6 weeks- 82.34

Explanation:

150-10%=135 (one week)

135-10%=125.50 (two weeks)

125.50-10%=112.95 (three weeks)

112.95-10%=101.66 (four weeks)

101.66-10%=91.49 (five weeks)

91.49-10%=82.34 (six weeks)
