Question

Which choice is an inequality for this sentence? A number decreased by 20 is greater than 15. Answer Options with 5 options A. 15 ≤n − 20 B. 15 > n − 20 C. 15 < n − 20 D. 15 > 20 − n E. 15 < 20 − n

Answer 1

A number decreased by 20 is greater than 15 :
n - 20 > 15
or
15 < n - 20

answer is 
 
C. 15 < n − 20

Answer 2

The correct option is C. 15 < n − 20

Given, we have a number (let say n) decreased it by 20 so it becomes n-20 which is also greater than 15, so the correct expression is,  $n-20 > 15$.

Now this expression is also written as $15<n-20$ and read as n-20 is greater than 15.

Hence the correct expression is in option C, $15<n-20$.
