Let's solve for k.
3kx+24=9x
Step 1: Add -24 to both sides.
3kx+24+−24=9x+−24
3kx=9x−24
Step 2: Divide both sides by 3x.
3kx / 3x = 9x−24 / 3x
k = 3x−8 / x
Answer:
k = 3x−8 / x
-----------------------------------
Let's solve for x.
3kx+24=9x
Step 1: Add -9x to both sides.
3kx+24+−9x=9x+−9x
3kx−9x+24=0
Step 2: Add -24 to both sides.
3kx−9x+24+−24=0+−24
3kx−9x=−24
Step 3: Factor out variable x.
x(3k−9)=−24
Step 4: Divide both sides by 3k-9.
x(3k−9) / 3k−9 = −24 / 3k−9
x = −8 / k−3
Answer:
x = −24 / 3k−9

Use the formula for finding axis of symmetry:
-b -25 -25
x = ------ ⇒ --------- = -------- = 2.6
2a 2(-4.9) -9.8
$67.50 for three pairs of pants. $97.50 for five pairs of jeans. For all of these the price would be $165.00
