Lets say, I bought 3 cakes in the store and I spent $300, how much does a cake cost? The equation representing that situation is the following, calling x the cake cost, our unknown factor: 3x = 300 we can solve this equation by dividing all equation by 3: x = 100 therefore each cake costs $100
I want to buy eight bracelets, I don't know how much each bracelet costs, but the final cost will be $39.67. The equation would look like this: 8 x <em>c</em> = 39.67 Where <em>c</em> equals cost. To find the answer I would do the following: 8 x <em>c </em>= 39.67 <em>c</em> = 39.67 / 8 <em>c</em> ≈ 4.95 Each bracelet costs about $4.95.
