Answer:
B) Net sales will increase.
Step-by-step explanation:
Net sales = total sales - sales returns and allowances
If the percentage of sales returns and allowances is reduced, then total net sales should increase. E.g. total sales are $100, sales returns and allowances are $4, then net sales = $96. If sales returns and allowances decreases to $2, then net sales will be $98.
Also, if the fee that credit cards charge decreases by 1%, net sales will also increase. Credit card fees decrease total sales, e.g. you sell $50 using credit card and the credit card company charges you $1.50, your total sales will be $48.50, but if the credit card company only charges $1, then total sales will be $49.
