Question

2. For the table, identify the independent and dependent variables. Explain the relationship using words, and an equation (equation example: C = 2s + 20).

Number of Snacks Purchased, “s” Total Cost, “C”
0 $18
1 $21
2 $24
3 $27

Answer 1

The independent variable in this table is the number of snacks purchased, denoted as "s". The dependent variable is the total cost of the snacks, denoted as "C".

The relationship between the independent and dependent variables can be described as follows: as the number of snacks purchased increases, the total cost also increases.

There is a linear relationship between the number of snacks purchased and the total cost. The equation relating the two variables can be represented as:
C = 3s + 18
