On Black Friday, you buy 7 DVD's and a season of The Walking Dead. The cost of The Walking Dead was $17.50. Your total bill before tax is $52.43. Write and solve an equation to find the cost of a DVD.

Question

How would I write an equation from this bit of information?

Answer 1

DVD=d

season of The Walking Dead =s

therefore,

7 DVD's=7d

A season of The Walking Dead=s

total bill=$52.43

so, 7d+s=$52.43
