Question

Lena's Coffee Shop makes a blend that is a mixture of two types of coffee. Type A coffee costs Lena S4.10 per pound, and type B coffee costs $5.95 per

pound. This month's blend used twice as many pounds of type B coffee as type A, for a total cost of $336.00. How many pounds of type A coffee were used?

Answer 1

Answer: Just bought 21 pounds of coffee A

Explanation:

• We know that she consumed twice as many pounds of Type B coffee as type A.

• Then let the total number of cafe feet A=x ; then the number of cafe feet B=2x .

• We also know that the total number of feet cost $336

• And the fact that one pound of coffee A costs $ 4.1 ; and one pound of coffee B costs $ 5.95

• Then :

• 
  `\large \boldsymbol {} 2x\cdot 5,95 +x\cdot 4,1 =336 \\\\ 11,9x+4,1x=336 \\\\ 16x=336 \\\\ \boxed{x=21}`
