Question

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

Answer 1

Again, brianna please post the ENTIRE question. We cannot give you help unless you do this.

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.

Thank you!. One second please

Answer 4

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

We know that the function for Alice's gross pay is : p(t) = 8t, where t is number of hours. So, 9 hours and 15 minutes would be equivalent to 9.25 hours as 15 minutes is 1/4 or .25 of a hour. Thus, we must evaluate p(9.25) or 8 * 9.25, which we get 74 as the result. Thus, Alice's gross pay after 9 hours and 15 minutes is 74 dollars.

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

Again, we know the function for Alice's gross pay is p(t) = 8t. This time we want to evaluate p(4 hours and 50 minutes) or p (29/6) [ this is because 4 and 50 minutes is equal to 4 and 5/6 or the improper fraction 29/6) When we evaluate this, we obtain 38.6666666666666667, which is equivalent to 38 and 2/3 dollars.
