Antonio just signed up for new phone plan and is comparing his fees to that of his friend Marcus. They both create equations so that they could compare their fees with each other.
Antonio's plan: Monthly cost 3 (.75m + 10) + 2.50m – 15 where m is the
number of minutes used
Marcus's Plan: Monthly cost 2 (1.75m + 12.50) – .75m + 4 where m is the
number of minutes used by setting their monthly cost equal, decide after how many minutes the two plans will cost the same

7 minutes

Step-by-step explanation:

Antonio's plan: Monthly cost

3 (.75m + 10) + 2.50m – 15

Marcus's Plan: Monthly cost

2 (1.75m + 12.50) – .75m + 4

where, m = number of minutes used by setting their monthly cost equal

3 (.75m + 10) + 2.50m – 15 = 2 (1.75m + 12.50) – .75m + 4

2.25m + 30 + 2.50m - 15 = 3.5m + 25 - .75m + 4

4.75m + 15 = 2.75m + 29

4.75m - 2.75m = 29 - 15

2m = 14

Divide both sides by 2

m = 14 / 2

= 7

m = 7 minutes

the answer is n

step-by-step explanation:

from the graph attached below:

domain of graph is the value of x for which the given function profit function p(x) is defined.

(a) the domain represents the number of years for which the outlet will earn a profit.

range of profit function defines the lowest to highest value of profit earned.

(b) the range of this function is (0 , 160 ). for this function, the range represents the outlet's profit earned.
