Solve this by dividing the 180 by 6. This results in 30. So, each number should be rolled 30 times. There are only two numbers greater than 4. Multiply 30 by 2 to get your answer, 60.
        
                    
             
        
        
        
Answer:
$5.67
Step-by-step explanation:
$5.67
Markup refers to the amount added to the cost price to cover overheads and profit. So for example a 50% markup on a $10 product would mean adding 50% of $10 onto the sale price. As fractions can be written as decimals (50% = 0.5) and we are adding on the amount of markup to the initial cost we can also phrase this as 10 x 1.5 = 15  
For your question, the markup would become 1.1 and the initial cost is 2.7, remembering we must add 1 to the markup to cover the initial cost  
2.7 x 2.1 = 5.67
