Answer:
If the cost is only variable, the proportion of the cost is wrong.
The proportionated cost should be of $10,062
Explanation:
Giving the following information:
An advertiser rents a rectangular billboard that is 21.5 ft wide and 13 ft tall. The rent is $12 per square foot. For a billboard three times as tall, the advertiser has to pay $30,186.
First, we need to calculate the cost of the first billboard:
Square foot= 21.5*13= 279.5sq
Total cost= 279.5*12= $3,354
Now, a billboard 3 times as tall:
Square foot= 21.5*(13*3)= 838.5
Total cost= 838.5*12= 10,062
<u>If the cost is variable, the proportion of the cost is wrong.</u>
