The number of students taking sophomore mathematics at Union College has been decreasing at the rate of 20 per year for many years. Assuming this trend continues, write a multiplication problem that describes the change in the number of sophomores taking mathematics at Union for each of the following:
a: The change over the next 5 years
b: The situation 5 years ago
c: The change over the next n years
d: The situation n years ago

clearly, at a change rate of 20 per year,
(a) 20(5) = 100
(b) 20(5) = +100
(c) 20n
(d) 20(n) = +20nposted by Steve

for A do 20x5 then for B 20x5 C 20xn then for D 20xn. I think this is correct but not 100% sure so please correct me if I am wrong.
