Answer:
Equation: m=21(p)
Difference: $5
Explanation:
To solve this, we first need to figure out an equation for Company R.
We know that Company S's equation is m=26(p). this means that the amount reimbursed is 26 times the amount of aluminum returned.
210/10=21
Company R's equation is m=21(p). We know this because throughout the table, the amount reimbursed is always 21 times more than the amount of aluminum returned.
Now that we have two equations, we can solve. 26-21=5.
Therefore, the difference between the amount reimbursed per pound is $5. (As long as there is not another variable, this should be the answer for part b)
All the best on your homework and I hope I didn't get anything wrong!
