The pattern that describes the table.

Let the pattern be z = mw + c

(3, 27) and (5, 45)

m = (45 - 27) / (5 - 3) = 18/2 = 9

Now,

(3, 27) = (w, z)

27 = 9 x 3 + c

A dinner cost $28.50 which included a 15% tip. How much was the tip?

Answers

Answer: $4.28

Tip: $4.275 = $4.28

Step-by-step explanation:

Use the formula: Tip = Tip% x Bill Total

In this case, the tip is 15% and the total bill is $28.50.

15% = 0.15

28.50 x 0.15 = 4.275

Answer:

$4.28
