I have an Amazon account that I pay a flat rate of $8 a month. With it, I get free movies and shows. However, any premium movie I purchase costs me $4 more. If I spent $24 last month, how many premium movies did I buy?
The equation would be set up as shown below:
(Let x represent the amount of premium movies I bought.)
4x + 8 = 24
next: subtract 8 from both sides = 4x = 16
then: divide both sides by 4, which gives us our answer = x = 4
So I purchased 4 premium movies.
