Answer:
The relation is <u>not</u> a function.
Step-by-step explanation:
A function is a relation in which no two ordered pairs have the same input and different outputs. Whenever you're trying to determine whether a given relation is a function, observe whether each input corresponds with <u><em>exactly</em></u> one output.
In this case, the answer is no. The input value of 10 corresponds with two output values, 4 and 20. It only takes one input value to associate with more than one output value to be <u>invalid</u> as a function.
Therefore, the given relation is <em><u>not</u></em> a function.
127.40/26 = $4.90 per pound
18 * 4.9 = $88.20
It would cost $88.20
$75.14. formula as follows ($79.99 - (($79.99/100)x12)) + ((($79.99/100)x12)/100)*6.75)
