To calculate this we simply need to devide 153 by 18.
153/18=8.5
which means that Sarah can buy 8 new CDs and will have
153 - 8*18=9 dollars spare.
Sarah has extra cash because with that spare money she can't buy whole new CD.
We need to remove either (1, 4) or (1, 1) to create a function.
<h3>How to alter a relation in order to obtain a function</h3>
Relations are formed by two sets, an input set known as domain and an output set known as range and relationships between these sets. A relation is a function if and only if each element from domain is related to only one element of the range. Mathematically speaking, we must satisfy the following proposition:
x → f(x), x → f'(x) ⇒ f(x) = f'(x)
Based on this definition, there are two possibilities to create a function:
- Remove (1, 4)
- Remove (1, 1)

Answer:
Set up trig ratio using tangent.
Tan theta = opp/adj
Tan theta = 500/800
Tan^-1 (500/800) = 32 degrees
if the price is 76.50 now then it was 84.15
