Question

May you please break down steps and explain how to get the answerthanks!

Answer 1

In the question, we are given the table below

We also know that one song cost $0.50 and one album cost $4. The total amount she has to download music is also given as $15.

If we let the number of songs be s and the number of albums be a. We can create an equation below as :

`0.50s+4a=15`

We can complete the table using the equation above.

When s =6, we have

`\begin{gathered} 0.50*6+4a=15 \\ 3+4a=15_{} \\ 4a=15-3 \\ 4a=12 \\ a=(12)/(4) \\ a=3 \end{gathered}`

When a = 1

`\begin{gathered} 0.50s+4*1=15 \\ 0.50s+4=15 \\ 0.50s=15-4 \\ 0.50s=11 \\ s=(11)/(0.50) \\ s=22 \end{gathered}`

When s= 30

`\begin{gathered} 0.50*30+4a=15 \\ 15+4a=15 \\ 4a=15-15 \\ 4a=0 \\ a=(0)/(4) \\ a=0 \end{gathered}`

We can then have the answers in order.

Answer A: Table

Answer B: Equation

`0.50s+4a=15`

Answer C: Graph
