Snowcat [4.5K]

Answer:

p = 2.7x - 20

p(90) = $223

Step-by-step explanation:

revenue → f(x) = 3x  ,where x is the number of downloads.

the statement “Your profit p is $20 less than 90% of the revenue for x downloads”

<u><em>means</em></u>

p=90\% f\left( x\right)  -20

<u><em>means</em></u>

<u><em></em></u>p=\frac{90}{100} \times f\left( x\right)  -20

<u><em>means</em></u>

p=\frac{9}{10} \times (3x)  -20

<u><em>means</em></u>

p=\frac{9}{10} \times (3x)  -20

<u><em>means</em></u>

p=2.7x -20

………………………………

the profit for 90 downloads :

= p(90)

= 2.7×(90) - 20

= $223
