Question

Harry operates a coffee shop. One of her customers wants to buy two kinds of beans. Arabian mocha and Columbian decaf. If she wants twice as much Arabian mocha as Columbian decaf how much of each can she buy for a total of $181.50?

The customer can buy ____ lbs of arabian mocha
And ______ lbs of Columbian decaf

Answer 1

• 11 lbs of Arabian Mocha
• 5.5 lbs of Columbian Decaf

Explanation:

Since we want twice as much Mocha as Decaf, we can create a "bag" that contains 2 lbs of Mocha (at 11.50 each) and 1 lb of Decaf (at 10). The value of this "bag" is then 2×11.50 +10.00 = 33.00. For 181.50, we can buy ...

181.50/33.00 = 5.5

"bags". This amount is ...

11 lbs of Arabian Mocha and 5.5 lbs of Columbian Decaf
