The Deep Dive

Let's solve this coffee mixing problem step by step! Let’s denote the pounds of Kenya coffee as \( x \) and the pounds of Mexican Shade Grown coffee as \( y \). According to the problem, you have two equations: 1. **Total Weight Equation**: \[ x + y = 25 \] 2. **Total Cost Equation**: \[ 14.50x + 11.60y = 12.76 \times 25 \] Substituting the second equation: \[ 14.50x + 11.60y = 319 \] Now, you can express \( y \) in terms of \( x \) using the first equation: \[ y = 25 - x \] Substituting \( y \) back into the total cost equation gives you: \[ 14.50x + 11.60(25 - x) = 319 \] Distributing the 11.60: \[ 14.50x + 290 - 11.60x = 319 \] Combine the \( x \) terms: \[ (14.50 - 11.60)x + 290 = 319 \] \[ 2.90x + 290 = 319 \] Subtract 290 from both sides: \[ 2.90x = 29 \] Divide by 2.90 to find \( x \): \[ x = \frac{29}{2.90} \approx 10 \] Now, substitute \( x \) back into the total weight equation to find \( y \): \[ y = 25 - 10 = 15 \] Thus, the coffee distributor should blend approximately **10 pounds of Kenya coffee** and **15 pounds of Mexican Shade Grown coffee** to create the desired coffee blend.
