Answer:

1. 60 degrees

2. 50 degrees

4. 49 degrees

5. 26 degrees

Step-by-step explanation:

The sum of the measures of the angles of a triangle is 180 degrees.

x + 80 + 40 = 180

x + 120 = 180

x = 60

x + 75 + 55 = 180

x + 130 = 180

x = 50

x + 90 + 41 = 180

x + 131 = 180

x = 49

x + 81 + 73 = 180

x + 154 = 180

x = 26

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.
