His total money is: $80
He spent $16 for the entrance of the fair and food.
80-(4+12) = 64
subtracting $1.25 per ride = -1.25x
Therefore gives the function:
f(x) = -1.25x + 64
Answer:
#1 and #3
Step-by-step explanation:
In this case the two equations<span> describe lines that intersect at one particular point. Clearly this point is on both lines, and therefore its coordinates (x, y) will satisfy the </span>equation<span> of either line. Thus the pair (x, y) is the one and only </span>solution to the system of equations<span>.</span>
Answer: Yes it is a function.
Step-by-step explanation: When trying to find out, you put it into a calculator and can tell by the line if it is a function.
$129.05 I think but I’m not sure
