Answer:
the answer is c
Step-by-step explanation:
x and y have to be at least 12, so that's why the greater than sign was used
the amount of money had to be at most $230, so that's why the less than sign was used
they said x and y represent black and white respectively, so that means x is black and y is white, so it is 18x and 20y
90/3 parts of silver = 30 times multiplied by
tin = 12 × 30 = 360g
lead = 8 × 30 = 240g
12.5 / 23 = 0.5434 parts per metal
tin = 12 × 0.5434 = 6.5kg
lead = 8 × 0.5434 = 4.5kg
silver = 3 × 0.5434 = 1.5kg
