Answer:
Reduction percentage is 62.8%
Maintained markup percentage is 86%
Step-by-step explanation:
Reduction percentage = (sales price - cost price)/cost price × 100 = (349.95 - 215)/215 × 100 = 0.628 × 100 = 62.8%
Maintained markup price = (marked price - cost price)/cost price × 100 = (399.95 - 215)/215 × 100 = 0.86 × 100 = 86%
