could you help me @mathmath333

Answer 3

where are the options

Answer 4

1. A(b) = b/250+3b
2. A(b) = 250+3b/b
3. A(b) = (250+3b) x (b)
4. A(b) = 250+4b

Answer 5

i think it is either 3 or 4

Answer 6

is options be this

\(\large \color{black}{\begin{align} A(b)=250+\dfrac{3b}{b} \hspace{1.5em}\\~\\
\end{align}}\)

or this

\(\large \color{black}{\begin{align} A(b)=\dfrac{ 250+3b}{b} \hspace{1.5em}\\~\\
\end{align}}\)

Answer 7

the second one

Answer 8

where there is a / im trying to say that everything befor that is above it

Answer 9

\end{align}}\)

Answer 10

yes

Answer 11

the average can be calculated when we divided the whole by number of times it occurs so it should be B
