Answer:
Notebook: 5$ each. Folder: 7.50$ each.
Step-by-step explanation:
A notebook costs 5$ more than a folder, and 3 notebooks were purchased, so we can safely say that at least 15$ was spent on notebooks. Then, take the remaining number after subtracting 15 from 30 and divide it by 2, assuming all of the folders are the same price.
You are given two sides and an angle.
Using SAS, would use the law of cosines.
a = √(10^2 + 11^2 - 2*10*11*cos(43))
a = 7.75
Round to 7.8
