Question

y=5+5x

Weeks (x) Magazines (y)
3
5
7

Answer 1

To find the number of magazines Judy has read after 3, 5, and 7 weeks based on the formula \( y = 5 + 5x \), we will substitute the values of \( x \) (the number of weeks) into the equation.

1. For \( x = 3 \): \[ y = 5 + 5(3) = 5 + 15 = 20 \]

2. For \( x = 5 \): \[ y = 5 + 5(5) = 5 + 25 = 30 \]

3. For \( x = 7 \): \[ y = 5 + 5(7) = 5 + 35 = 40 \]

Now we can fill in the table:

\[ \begin{array}{|c|c|} \hline \text{Weeks } (x) & \text{Magazines } (y) \ \hline 3 & 20 \ 5 & 30 \ 7 & 40 \ \hline \end{array} \]

So the completed table is:

• After 3 weeks: 20 magazines
• After 5 weeks: 30 magazines
• After 7 weeks: 40 magazines
