Step-by-step explanation:
The domain of a step function is all real numbers.
Answer and explanation
a is $18.00 because Z is a constant
b is y=2.50x+18.00
c is that y=2.50x+z turns into y=$55.50 and then x=15 which we substitute
that leads to 55.50 =2.50(15)+z
and the untimely z = 18.00 dollars .
X=15 this is because 45+15 is equal to 60 and is equal to 4x so 4x=60 divide both sides by 4 to get x and you get x is equal to 15
The last one is the right answer
