Answer:
The profit is $16
Step-by-step explanation:
From the question, we have 20 kg at Birr y per kg
The cost price is thus;
20 * y = 20y Birr
Now for the selling price;
16 kg was sold at (y + 3/4) Birr per kg
we have here that;
16 * y + 3/4 * 16
= 16y + 12
The rest is thus; 20 - 16 = 4 kg
The rest of this at (y + 1) per kg will be
4 * (y + 1) = 4y + 4
The total selling price is thus;
4y + 4 + 16y + 12 = 20y + 16
The profit is the difference between the selling and cost price
We have this as:
20y + 16 - 20y
= $16
