Abicycle helmet cost $41.40 in 1983. what will a bicycle helmet cost when the cpi is 186? round to the nearest cent. a. $222.58 b. $144.60 c. $77.00 d. $72.30

Option C. $77 is the correct option.

Step-by-step explanation:

CPI (consumer price index) is calculate as CPI = (Price of goods in a year/Price of the goods in the base year)×100

Now base year is 1983 so price of helmet in 1983 = $41.40

CPI = 186

By putting these values in the formula

186 = (Price of the helmet / 41.40)×100

Price of the helmet = (41.40×186)/100 = $77

Option C. $77 is the answer.

answer: x= -2y

step-by-step explanation:

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.
