Quick and explain. i'm offering 25pts and brainliest answer

A. Subtract the difference between the two columns for two sets of numbers:

30-20 = 10

135 -110 = 25

40-30 = 10

160 - 135 = 25

So for every 10 t-shirts the total cost raises by 25

25 / 10 = 2.50 per t-shirt.

The starting cost is when 0 t shirts are sold.

110 - 50 = 60

The equation would be C = 2.50n + 60

( Multiply 2.50 by the number of t-shirts sold and then add the starting cost of 60).

B. See attached picture.

C. Using the equation from A replace n with 120:

C = 2.50(120) +60

C = 300 + 60

C = 360

It would cost $360.00

answer:

the position of equilibrium will shift to the left.

step-by-step explanation:

the general equation for the dissociation of a weak base is

b + h₂o   ⇌   bh⁺ + oh⁻

according to le châtelier's principle, when a stress is applied to a system at equilibrium, the system will respond in a way that tends to relieve the stress.

if you apply a stress by adding more bh⁺ or oh⁻,   the system will respond by moving in a direction that gets rid of the added ions.

the position of equilibrium will shift to the left, forming more of the undissociated base.
