Answer:

Step-by-step explanation:

Hey There!

Angle 3 and Angle 4 are a pair of supplementary angles meaning that added together they will equal 180

So if angle 4 is given to find angle 3 all we have to do is subtract the angle that is given from 180

180-138=42

Therefore angle 3 = 42

Each year Lizzie’s school purchases student agenda books, which are sold in the school store. This year, the school purchased 35

Stells [14]

The school can charge $7.54 for each agenda book.

Step-by-step explanation:

Given,

Purchase price of 350 books = $1137.50

Profit they want to make = $1500

Total amount = 1137.50 + 1500 = $2637.50

Therefore;

The school must sell 350 books for $2637.50

Thus,

350 books = 2637.50 dollars

1 book = $\frac{2637.50}{350}$

1 book = $7.535

Rounding off to nearest cent

1 book = $7.54

The school can charge $7.54 for each agenda book.
