$\bf 15x^2-24x+9\div 3x-3\implies \cfrac{15x^2-24x+9}{3x-3}\implies \cfrac{\underline{3}(5x^2-8x+3)}{\underline{3}(x-1)}
\\\\\\
\cfrac{5x^2-8x+3}{x-1}\implies \cfrac{(5x-3)\underline{(x-1)}}{\underline{(x-1)}}\implies 5x-3$

Problem 2: Raylin wants to buy a new bike for $85. She already has $22 saved and her mom will

ohaa [14]

<h2>○=> <u>Correct option</u> :</h2><h2> $\color{plum}\tt\bold{(d) \: 25}$ </h2><h3>○=> <u>Steps to derive correct option </u>:</h3>

Cost of a bike Raylin wants to buy = $85

Money Raylin already has = $22

Money she needs :

$= \tt85 - 22$

$= \tt\$63$

Thus, money Raylin still needs = $63

Money she gets from doing one chore = 2.50

Number of chores the needs to do :

$= \tt \frac{63}{2.50}$

$\color{plum} =\tt 25 \: chores$

Thus, Raylin needs to do 25 chores to be able to buy the bike.

Therefore, the correct option is <em>(d) 25</em>
