Question

Hello I need help with this :) also option D: If 4 more students sign up, the total fees will be greater than $700.

Answer 1

Given

There are 11 students signed up and the fee is $45 per student.

And,

`45(11+n)\ge700`

To find the true statement.

Now,

It is given that,

`45(11+n)\ge700`

Then,

`\begin{gathered} 45(11+n)\ge700 \\ 11+n\ge(700)/(45) \\ 11+n\ge15.55 \\ n\ge15.5-11 \\ n\ge4.5 \end{gathered}`

Hence, the true statement is, the number of additional students needed is 5 or more.
