Question

Tina bought 6 plates and 2 glasses. Each plate costs $6.99, and each glass costs $22.98. Write an equation representing the total cost C.

Answer 1

To calculate the total cost C that Tina spent, multiply the number of plates and glasses by their respective costs and sum these amounts. The equation is C = (6 × $6.99) + (2 × $22.98), which equals C = $87.90.

Step-by-step explanation:

The total cost C that Tina spent on 6 plates and 2 glasses can be written as an equation by multiplying the number of each item by its respective cost and then summing these amounts. The cost of each plate is $6.99 and the cost of each glass is $22.98. Therefore, the equation representing the total cost C is:

C = (Number of Plates × Cost per Plate) + (Number of Glasses × Cost per Glass)

C = (6 × $6.99) + (2 × $22.98)

C = $41.94 + $45.96

C = $87.90

So, the equation representing the total cost C is C = $87.90.
