Answer:
N(h) = 2h + 6
Step-by-step explanation:
A model of the number of people that Denis can invite to his party:
N(x) = x/25.............(1)
Where x = amount of money saved
Amount of money saved can be modeled by the equation:
M(h) = 50h + 150...........(2)
In the above model, h = number of overtime hours
M(h) = amount of money saved = x
Therefore equation (1) can be re - written as:
N(x) = M(h)/25.................................(3)
Substituting equation (2) into equation (3)

Find an explicit expression that models the number of people that Denis can invite to his party if he worked h overtime hours this week can be expressed as:
N(h) = 2h + 6

Answer:
x = 30
Step-by-step explanation:
Let's set up an equation to represent this problem:
2/5 * x + 15 = 27
subtracting 15 from both sides,
2/5 * x = 12
Multiplying 5/2 to both sides,
5/2 * 2/5 * x = 12 * 5/2
1*x = 30
x = 30
