The monthly revenue of a digital magazine from each user is represented by f(x) = 2x+15. the monthly cost to provide the digital magazine to each user per month is represented by g(x) = x2. which of the following evaluates the profit function for each user of the digital magazine after 3 months? (f – g)(3) = (2(3) + 15) – 32 = 21 – 9 = $12 (g – f)(3) = 32 – (2(3) + 15) = 9 – 21 = −$12 (f + g)(3) = (2(3) + 15) + 32 = 21 + 9 = $30 (g – f)(3) = 32 – 2(3) + 15 = 9 – 6 + 15 = $18

step-by-step explanation:

in standard form:

a= dictionaries

b= maps

you have to buy 3 dictionaries, so put a 3 next to the a (dictionaries) so that you can multiply them by each other.

a3+b= 60 (the amount of money you have)

we already know the cost of a=15 so replace a with $15

($15 x 3)+b=60

multiply 15 and 3 to get $45 and replace it with $45

45+b=60

and then replace b with 15 to get the total:

45+15=60

that means you have $15 left after buying 3 dictionaries.

15 divided by the cost of a map ($5) equals 3.

so you can buy 3 maps.

sorry if it was confusing!
