Eva buys online tickets to a play for her family. each ticket costs $45.00 and there is a fee of $17.99. the total cost for tickets including the fee is $422.99. how many tickets does eva buy?

45.00x +17.99 = 422.99 (Setup Equation)

45.00x = 405 (Subtract 17.99 from both sides)

x = 9 (Divide both sides by 45.00)

9

Step-by-step explanation:

First, you write out the equation. We don't know how many tickets Eva bought, so it can be represented by x. Each ticket costs 45 dollars. The amount of tickets times 45 plus the fee will equal 422.99, so the equation will look like this:

45x + 17.99 = 422.99

Subtract 17.99 from both sides:

45x = 405

Divide 45 on both sides:

x = 9

Eva bought 9 tickets
