Step-by-step explanation:
Installation fee equation will be added onto the original equation
So g = base cost + percent cost + $100
(Cost of carpet) ---> g = $7.5x + ($7.5x * 0.05) + $100
Plug in 150 into the formula that gives you $1281.25

Answer:
Therefore there are 35 number of 2-point questions and 15 number of 5-point questions.
Step-by-step explanation:
i) let the number of 2 point question is x.
ii) let the number of 5 point questions be y
iii) total number of questions is 50
iv) therefore x + y = 50
v) it is also given that 2x + 5y = 145
vi) solving for the two equations found in iv) and v). Multiplying iv) by 2 we get
2x + 2y = 100
vii) subtracting equation vi) from equation v) we get 3y = 45.
viii) Therefore y = 15.
ix) using the value in viii) and substituting in iv) we get x + 15 = 50.
Therefore x = 50 - 15 = 35
x) Therefore there are 35 number of 2-point questions and 15 number of 5-point questions.
F+g(x) = f(x) + g(x) = 3x-1 + x+2 = 4x+1
