Question

You want to get at least 48 people to your costume party. Your 12 best friends will definitely be there. For every time you tweet about it, 4 more people will come. How many tweets do you need to send to get at least 48 people?
Write the equation and solve for the unknown. Then check your answer.

Answer 1

The number of tweets that's will be needed to send to get at least 48 people will be at least 9 tweets.

Let the number of tweets be represented by x.

Therefore, based on the information given, the equation to solve the question will be:

12 + (4 × x) ≥ 48

12 + 4x ≥ 48

Collect like terms.

4x ≥ 48 - 12

4x ≥ 36

x ≥ 36/4

x ≥ 9

Therefore, 9 or more tweets will be needed.
