Answer: The correct answer is B.
Step-by-step explanation: We are given the cost of restaurant meal of M. Clark is $25.50.
and she has given 20% of the meal's cost as a tip to the waiter.
Step 1: Calculating the amount of tip paid
Total tip paid = $5.1
Step 2: To find the total amount, we add the cost of the meal and the tip paid
Total amount = Cost of the meal + Tip paid
Total amount = $25.50 + $5.10
Total amount paid by Ms. Clark = $30.6

Answer:
- 100 pounds Earl Grey
- 300 pounds Orange Pekoe
Step-by-step explanation:
Let x represent the number of pounds of Earl Gray tea in the mix. Then the total cost of the mix is ...
6x +4(400-x)=4.50(400)
2x +1600 = 1800 . . . . . . . simplify
2x = 200 . . . . . . . . . . . subtract 1600
x = 100 . . . . . . . . . . . divide by 2. Pounds of Earl Grey
(400 -x) = 300 . . . . . Pounds of Orange Pekoe
The blend should have 100 pounds of Earl Grey and 300 pounds of Orange Pekoe.

<em>Additional comment</em>
It is easy to show that the relationship between the quantities of high-cost (H) and low-cost (L) items in the mix (M) is ...
fraction of mix that is H is (M -L)/(H -L)
Here, we have H=6, L=4, M=4.5, so the fraction of the mix that is Earl Grey is ...
(4.5 -4)/(6 -4) = 0.5/2 = 0.25
There are 400 pounds of mix, so 0.25(400) = 100 pounds is Earl Grey.
The solution above is essentially 2-step, so using this relation doesn't necessarily save any steps. It just makes it possible to solve the problem in your head.
