Simplify the problem down, so:
m = 12 & n = 5
m = 6 & n = 2.5 <span>(divided each number by 20)
</span>
Now m is a factor of 18. Multiply each number by 3.
Answer: m = 18 & <span>n = 7.5</span>
He would need to sell 28 because
12.50*28=350 and 350+50=400

=
So that means B is one of the correct answers.
To find the other correct value, you can divide the two fractions as stated in the question:
by
= 
81 is equivalent to 3⁴
So that means E is also correct.

Since we know that a - 2 will equal 8, it is safe to assume that 8 + 2 = 10. Therefore a=10.
