Question

Suppose you have 30 CDs. You know that you have 11 more CDs than your friend. Write and solve an equation to find the number of CDs your friend has. Question 3 options: n – 11 = 30; 41 30 + n = 11; –19 30 + 11 = n; 41 n + 11 = 30; 19

Answer 1

n+11=30;19 is the best answer. Since your total is 30 and you have 11 more it would only make since to either subtract 11 from 30 or find out what needs to be added to 11 to make 30.

Answer 2

n+11=30

n = 19

Explanation:

You have 30 CDs and you friend had n amount of CDs. We also know that you have 11 more CDs than your friends. Therefore we can write expression as:

`n+11=30` and simplify

`n =30 -11`

`n=19`

Therefore you friend will have 11 CDs which is 11 less than what you have.
