Mike is buying eight tickets for a concert. A package of five tickets costs $74.45. Individual tickets cost $17.25 each. What is
svetlana [45]

Answer:

$126.20

Step-by-step explanation:

<u><em>Given:</em></u>

<em>Mike is buying eight tickets for a concert. </em>

<em>A package of five tickets costs $74.45. </em>

<em>Individual tickets cost $17.25 each.</em>

<u><em>To Find:</em></u>

<em>What is the least amount that Mike can pay for eight tickets? Be sure to include a decimal point in your answer.</em>

<u><em>Solve:</em></u>

<em>Since we know that:</em>

<em>A package of five tickets costs $74.45. </em>

<em>Individual tickets cost $17.25 each.</em>

<em>Hence we know that 5 + 3 = 8</em>

<em>Thus,</em>

<em>$74.45 = 5 tickets</em>

<em>Now for the 3 tickets we can do individual tickets which cost $17.25</em>

<em>$17.25 × 3 = 51.75</em>

<em>Then we add both together:</em>

<em>51.75 + 74.45 = $126.20</em>
