Answer:
y = 25x+100
Step-by-step explanation: You are paying 25$ times how many months he stayed there, plus a 100 dollar sign up fee, so y = 25 dollars per month, plus 100 dollars.
1. 6+ -35 = -29
2. -29+ 6 = -35
1. 37 + -33 = 4
2. -33 + 4 = 37
For this case we have the following variable:
p: cost of the item that Arthur wants to buy before tax
The expression for the 6% tax is given by:
Or equivalently:
Therefore, two different expressions for the total cost are:
Expression 1:
Expression 2:
To prove that they are equal, suppose that the item costs $ 100:
Expression 1:
Expression 2:

Since the cost is the same, then the expressions are the same.
Answer:
Two different expressions that model the problem are:
