Question

What is P (13)? What does it mean? Explain how you could use the graph, the table, or the formula to compute P (13).

Answer 1

What's the entire problem?

Answer 2

Alice is paid $8 per hour in her part-time job. Let t be the amount time that she works, in hours, during the week, and let P ( t ) be her gross pay (before taxes), in dollars, for the week.

Write a formula showing how her gross pay depends upon the amount of time that she works. Answer: P (t) = 8t, where t is the number of hours.

What is P (13)? What does it mean? Explain how you could use the graph, the table, or the formula to compute P (13). Answer: P (13) means her gross pay before taxes. But P (13) = 104

If Alice works 9 hours and 15 minutes, what will her gross pay be? Show how you know. Express the result using function notation.

If Alice works 4 hours and 50 minutes, what will her gross pay be? Show how you know. Express the result using function notation.

Answer 3

P(13) is where she's worked 13 hours during her week. P(13) would be 13*8=104.

Answer 4

15 min=1/4 an hour
so 9.25*8 = $74

and 50 min = 5/6 an hour

4.83333333333333333333333333333333*8 = about 38 and 2/3, so $38.67

Answer 5

function notation
f(x) = 8x
f(4.8333333(repeating) = 38.6666(repeating)

Answer 6

what about the last one ???

Answer 7

i just did that one

Answer 8

P (t) = 8t
P(13) = 8(13)
P(9.25) = 8(9.25)
P(4.83) = 8(4.83)

Answer 9

yes, exactly.

Answer 10

t = hrs
