Answer:

$m\widehat {MP} =46\degree$

Step-by-step explanation:

By inscribed angle theorem:

$m\angle MQP=\frac{1}{2} \times \widehat {MP}$

$23\degree =\frac{1}{2} \times m\widehat {MP}$

$23\degree \times 2= m\widehat {MP}$

$m\widehat {MP} =46\degree$

A grocer bought n eggs at $x each. He marked up the price of each egg by $y and sold all of them. Find the sales amount, express

Alex777 [14]

Answer:

Sales = n $\times$ ($x + $y)

Step-by-step explanation:

The basic simple sales equation is

Quantity $\times$ Price = Sales

Here in the given question,

Total quantity of sales = n

Price = Cost + markup

(Markup refers to the profit added to cost)

Thus price = $x (cost) + $y (markup)

Sales = n $\times$ ($x + $y)

Sales amount is the total amount received from sales of products, total quantity at some price provided.
