I believe its area I'm doing the same thing
James received an average tip of 16% for the meals he served, calculated by dividing his total tips by his total bill amount and multiplying by 100.
To solve this problem, we first need to find the total amount of bills that James served, which is $23.59 + $40.65 + $30.50 + $15.68 = $110.42. James received a total of $17.67 in tips. The percentage of tips James received can be calculated by dividing the total amount of tips by the total amount of bills he served and then multiplying that result by 100 to get the percentage. So, the calculation would look like this:
($17.67 / $110.42) × 100 = 16.01%
Rounding to the nearest percent, James received an average of 16% tip for serving these meals.

Answer:
the function's period
Step-by-step explanation:
A periodic function has the same values in the same sequence for each period of the function. The nail will return to the same orientation after any integer number of full periods of the function.
A. 19 B. 17 C. -11 D. 21
The given expression is 5a+5b The given values of a and b are a=-6 ,b=-5
Substituting the values of a and b in the expression we have :
5a+5b= 5(-6)+5(-5)
= -30 -25 ( when a positive and a negative number is multiplied the result is a negative number)
-30-25=-55 (same signs are added)
The answer to the expression 5a+5b when a=-6 anf b=5 is -55.
