Final answer:
Peter pays $40 a month for a membership to a frozen yogurt shop that allows him to only pay $3 for each frozen yogurt regardless of size and number of toppings.
Step-by-step explanation:
Peter pays $40 a month for a membership to a frozen yogurt shop. With this membership, he only pays $3 for each frozen yogurt, regardless of size and number of toppings.
To find out how many frozen yogurts Peter can buy with his membership, we can divide the amount he pays for the membership by the cost of each frozen yogurt. So, 40 / 3 = 13.33. This means Peter can buy approximately 13 frozen yogurts with his membership each month.
Since Peter can buy a fixed number of frozen yogurts for a fixed price, we can say that the cost of each frozen yogurt is constant. This concept is related to the mathematical concept of a linear relationship, where the cost of frozen yogurts is directly proportional to the number of frozen yogurts purchased.
