Answer:
Effect on income= $9,600 increase
Step-by-step explanation:
Giving the following formula:
Unitary contribution margin= $90
The marketing manager believes that a $7,500 increase in the monthly advertising budget would result in a 190 unit increase in monthly sales.
To calculate the effect on income, we need to use the following formula:
Effect on income= increase in total contribution margin - increase in fixed costs
Effect on income= 190*90 - 7,500
Effect on income= 17,100 - 7,500
Effect on income= $9,600 increase
