Michael bought six books that cost d dollars each. Write an equation that can be used to show the total cost (c)of the books?How much would Michael spend if each book cost $7.89?

Equation: c = 6d

Total cost: $47.34

Step-by-step explanation:

Equation:

c = 6d

Where c is the total cost and d is the price a book

In order to find the total cost, you must multiply the price of something by the number of items you bought; therefore the equation above accurately represents the problem.

Substitute:

c = 6d

c = 6(7.89)

Multiply:

c = 6(7.89)

c = 47.34

In conclusion, Michael would spend $47.34 on 6 books.

Hope this helps :)
