estimete the solution of an equation

Question

casey bought 9 tickets to a concert. the total charge was $104, including a $5 service

1. write an equation you can solve to find c the cost of one ticket.

 

2. Explain how you could estimate the solution of your equation

 

3.- Solve the equation. How much did each ticket cost?

 

Answer 1

1.   $104 (total cost of tickets)-$5 (service fee)= Cost (C)

                         9 tickets                                    ticket

 

2. Estimate by rounding to even numbers: Subtract $4 instead of $5 to make it an even $100. Then round up to make 9 tickets, 10 tickets. Now you have easy numbers. $100/10 tickets equals about $10.

 

3. $104 (total cost of tickets)-$5 (service fee)= Cost (C)
                      9 tickets                                     ticket

 

STEP 1: Subtract $5 from $104 = $99

 

                  $99        = Cost (C)
                9 tickets       ticket

 

STEP 2: Divide $99/9 = $11

 

THEREFORE: The Cost/ticket = $11

 

Hope this helps!!
