<span>K) = 4/51 since there are four aces in the deck but only 51 cards left after the king has been removed. WITH REPLACEMENT: Find the probability of drawing three queens in a row, with replacement. We pick a card, write down what it is, then put it back in the deck and draw again.</span>
The simplified expression is 40 + 25e
<h3><em><u>
Solution:</u></em></h3>
Given that, Riley’s parent got a cell phone plan that has a $40 monthly fee for the first phone
For each extra phone,
Phone service charge = $15
Text service charge = $10
<em><u>The expression that represents the total phone bill in dollars is given by:</u></em>
40 + 15e + 10e
Where "e" is the number of extra phones
We are asked to simplify the expression
Combine the like terms. Here like terms are 15e and 10e
Therefore, add 15e and 10e
Thus the simplified expression is 40 + 25e
