Answer 1

Part a (given): 70 is 140% of 50.

Part b answer: 10 jackets.

Explanation:
- The markup found in part a is 140% of cost, so she charges 140% of $25 for each jacket: 1.40 × $25 = $35 per jacket.
- To have total sales at least $340: 340 ÷ 35 = 9.714... so she must sell a whole number, at least 10 jackets.
- Total from 10 jackets = 10 × $35 = $350 ≥ $340.
