Answer:
The ratios must be 88% of grade A sugar and 12% of grade B sugar.
Step-by-step explanation:
On the grade A every kg costs £75, while on the grade B every kg costs £50. The final mixture we want to make needs to cost £72 per kg. We will sum a certain mass of grade A, "x", with a certain mass of grade B, "y". The sum of these masses must be equal to 1 kg. So we have:
Since we want the final mixture to cost £72, we need to satisfy:
Solving the system of equation will reveal the ration that must be used.
The ratios must be 88% of grade A sugar and 12% of grade B sugar.
