Final answer:
The equation representing the total cost T of Mr. Wagner's trip to the grocery store, where he buys 5 oranges at a cost of c dollars per orange, is T = 5 × c.
Step-by-step explanation:
If Mr. Wagner is buying 5 oranges at a cost of c dollars per orange, we can calculate the total cost T of the trip to the grocery store using the formula for the total cost of purchasing a specific number of items at a given price per item. According to the information provided in the chapters, to compute the amount spent on each fruit in each year, you multiply the quantity of each fruit by the price. Applying this to Mr. Wagner's purchase:
T = number of oranges × cost per orange
Given that he is buying 5 oranges and each orange costs c dollars, the equation representing the total cost T is:
T = 5 × c
In this case, if c is the cost per orange, and Mr. Wagner buys 5 oranges, then his total cost T would be 5 times c.
