Myra saved $15 a month for 18 months. She bought a book for $46.50 and a tennis racquet for $129.95. How much does she have left?

Amount left with Myra is $93.55

Myra saved money $15 a month for 18 months.

So total money saved = Number of months × amount saved in a month.

It means Myra has spent total amount = 46.50 + 129.95 = $176.45

Now remaining amount with her = Total amount saved - Total amount spent

                                                     = 270 - 176.45 = $93.55

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.
