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”

Hi there! So, there's -4 and that is being multiplied by -1/4, which is it's reciprocal, because it's -4 flipped over. It's definitely not C or D. There is no addition, so it's not B. The only answer that truly makes sense is A, so the answer is A.
You’re trying to get the first equation to equal y so you can substitute it in the second question
2x + y = -2
subtract 2x from both sides: y = -2 - 2x
rearrange the equation : -2x -2
so the answer is C
The answer would be 27/14
