Consider yourself as an entrepreneur at the mall selling 6000 donuts a day at 50¢ each. When you raised the price to 70¢ each, the sale dropped to 5000 donuts per day. Assume that
there is a linear relationship between the price and number of donuts sold. Further assume that
there is a fix cost (overhead) of $1000 per day and the cost of each donut is 25¢. What would be
the price of the donut to maximize the profit?

P= $ 97.5

Step-by-step explanation:

option a is correct.

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have
