s=0 cost =$25 s=1 cost=$41 s=2 cost =$57 s=3 cost=$73 Let s stand for sets of prints ordered. write the RULE that describes a student's total cost.
s steps: 1 1 1
c steps: 16 16 16
looks like c = 16s+25
To find the rule that describes a student's total cost, we need to analyze the pattern between the number of sets of prints ordered (s) and the corresponding cost.
From the given information, we can observe that each time the value of s increases by 1, the cost increases by $16. This indicates that there is a constant rate of change between s and cost.
So, the rule that describes a student's total cost can be formulated as follows:
Total Cost = $16 * s + Initial Cost
In this case, the Initial Cost corresponds to the cost when no sets of prints are ordered (s=0). From the given data, we can determine that the Initial Cost is $25.
Therefore, the final rule that describes a student's total cost is:
Total Cost = $16 * s + $25
