Answer:
Store Z has the best sale price of $28
Step-by-step explanation:
Starting Price = $35
Store X offers 15% off = only 5.25$ off (0.15 * 35 = 5.25, 35 - 5.25 = 29.75) Final Price = $29.75
Store Y offers $5 off = only 5$ off (35 - 5 = 30) Finaly Price = $30
Store Z offers 1/5 off = only 7$ off (1/5 = 0.20, 0.20 * 35 = 7, 35 - 7 = 28) Final Price = $28 (BEST PRICE)
