The total price of 5 pounds of regular coffee and 3 pounds of decaffeinated coffee was $21.50. What was the price of the 5 pounds of regular coffee?
(1) If the price of the 5 pounds of regular coffee had been reduced 10 percent and the price of the 3 pounds of decaffeinated coffee had been reduced 20 percent, the total price would have been $18.45.
(2) The price of the 5 pounds of regular coffee was $3.50 more than the price of the 3 pounds of decaffeinated coffee.

We can create the equation:
5r + 3d = 21.5
We need to determine 5r.
Statement One Alone:
If the price of the 5 pounds of regular coffee had been reduced 10 percent and the price of the 3 pounds of decaffeinated coffee had been reduced 20 percent, the total price would have been $18.45.
We can create the equation:
5(0.9r) + 3(0.8d) = 18.45
4.5r + 2.4d = 18.45
45r + 24d = 184.5
Multiplying the equation in the stem analysis by 8, we have 40r + 24d = 172. Subtracting this from the equation above, we have:
5r = 12.5
Therefore, we see that the value of 5r is 12.5. Statement one alone is sufficient to answer the question.
Statement Two Alone:
The price of the 5 pounds of regular coffee was $3.50 more than the price of the 3 pounds of decaffeinated coffee.
We can create the equation:
5r = 3d + 3.50
3d = 5r - 3.50
Substituting 5r - 3.50 for 3d in the equation in the stem analysis, we have:
5r + 5r - 3.50 = 21.5
10r = 25
5r = 12.5
We see that the value of 5r is 12.5. Statement two alone is sufficient to answer the question.
Answer: D
5r + 3d = 21.5

We're given that 5*regular + 3*decaf = 21.5 and asked to calculate 5*regular
So we need to know 3*decaf or to have another equation with both variables.
We'll look for this information, a Logical approach.
(1) gives another equation with both variables -- sufficient! (it gives 5*regular*0.9 + 3*decaf*0.8 = 18.45)
(2) this also gives another equation with both variables. Sufficient.
(D) is our answer.
