Answer: 26.5% increase
Explanation:
Current profit = Sales - Variable costs - fixed costs
= ((32.50 - 16.50) * 360 bears) - 1,420
= $4,340
Sales increase by 20% = 360 * ( 1 + 20%) = 432 bears
New profit;
= ((32.50 - 16.50) * 432 bears) - 1,420
= $5,492
Effect of sales increase = ( 5,492 - 4,340) / 4,340
= 26.5% increase
