1) It tells you in the question c = cost, so cost would be the answer
2) 2.75 is the fixed rate so we would keep it as is. C is the cost which would the total, so c = ?m + 2.75
0.40 per half mile so you put 0.40m because it varies depending on the amount of miles
That makes the equation c = 0.40m + 2.75
3) Now to find how much it costs for 45 miles, you plug 45 for m
c = 0.4 * 45 + 2.75
c = 20.75
Not sure why it isn't an option
2 (b)>20
Because if b=11 than 2 (11)=22 and 34+22=56 and 56>54
Answer:
i think 2 5/12
Step-by-step explanation:
The total cost for video rental, f(n), is the sum of the membership fee and the cost of renting video game. The latter is the product of cost per video game times n video games. The correct equation used to represent the total cost is,
f(n) = 20 + 2n
Since the membership is increased by 15, the new equation is,
f(n) = 35 + 2n
Answer: (-3,-4x)
Solve for the first variable in one of the equations, then substitute the results into the other equation.
