Ok so first, you add $8.50, $10.25, and $2.25 to get the total bill of $21. Since 3 people are splitting the bill equally, divide $21 by 3 to get $7. Hope this is helpful!
cos(37°15') = cos(37.25°) ≈ 0.7960
15' means 15/60 of a degree, or 0.25 degrees.

The compound inequality is: x<20 and x>10
Given, a quantity of x is greater than 10 and less than 20.
A compound inequality (also known as a compounded inequality) is created when two or more inequalities are coupled with and. One part of an inequality must be true for a value to be a solution to an or inequality. It must make both parts true in order to be the solution to an inequality. X<3 or X>2, for instance.
Divide a compound inequality into two independent ones before attempting to solve it. Choose either a union of sets ("or") and an intersection of sets as the appropriate response ("and"). Then, resolve the graph and all inequalities.
Simply put, a compound inequality is more than one inequality that we want to address simultaneously. When referring to the resolution of both inequalities, we can either use the term "and" or "or."

P + o = 40 (where p = peak and o= off-peak)
30p + 12o = 876
This can be done using elimination or substitution.
I will do elimination.
Multiply the first equation by -12. This will 'eliminate' the variable o.
-12p -12o = - 480
30p + 12o = 876
Now add the two equations together.
18p = 396
Divide both sides by 18
p = 22
40 - 22 = 18
Peak hrs. = 22
Off-Peak = 18
CHECK 22(30) + 18(12) = $876
