1) In the problem we are given the rate of change which is $145 per night (slope) and a point. We are looking for an initial value or y-intecept (b value). We will write an equation in function form. We are also given a point, where 3 nights is our x variable or independent variable and $585 is represented by the y-variable or dependent variable.

It cost $150 for the family to go to the waterpark this is the intial value or y-intercept. It cost $50 per person to go to the waterpark because it is $150 for the family of 3.

2) In this problem we will be using standard form for the equation, we have two rates and a total amount. We will let x represent the number of sodas and y represent the number of bags of popcorn. The equation will be: 2x + 3y = 30 Possible combinations of number of sodas and number of bags of popcorn you could purchase for $30.
