a bookstore costs $120 a day to keep open, and it spends $14 for each book that it sells. 11
each book sells for $20, what is the break-even point for this bookstore

The break-even point for this bookstore is 20 units

Explanation:

We know that break even point is given by the following formula,

Here, we are given that bookstore costs $120 per day to keep open so fixed cost = 120$

Price per unit = price of each book =20$ and

variable cost = $14

Substituting these in the formula, we get

=   = 20

20 units which is the The break-even point for this bookstore.

answer: (c) m∠qpo + (2x + 16)° = 180°

step-by-step explanation:

the opposite angles of a quadrilateral are supplementary.

so, ∠o + ∠q = 180°   and   ∠p + ∠r = 180°

since ∠r = 2x + 16°, we can use substitution as follows:

∠p + ∠r = 180°

∠p + (2x + 16)° = 180°
