Complete the following question:

1. A store owner purchases mountain bikes from the manufacturer for $132.95. He sells the bikes for $217.99. What is the percent markup for the bikes?
   
   Hint:
   
   Step 1: Calculate the markup, in dollars.
   markup amount = store price – manufacturer price
   
   Step 2: Calculate the percent increase (percent markup).
   \(\text{percent increase}=\frac{\text{amount of increase}}{\text{original amount}}\times \text{100%}\)


2. The cost of dog food has increased in the last 3 months. A bag used to cost $17.99, but now the same sized bag costs $19.49. What is the percent markup on the dog food?

   Hint:
   
   Step 1: Calculate the markdown, in dollars.
   markdown amount = original price – final price
   
   Step 2: Calculate the percent decrease (percent markdown).
   \(\text{percent decrease}=\frac{\text{amount of decrease}}{\text{original amount}}\times \text{100%}\)
