Read the following description of a relationship: \[ \begin{array}{l}\text { Whitney has a superhero lunch box collection with } 20 \text { lunch boxes in it. From } \\ \text { now on, she decides to buy one new lunch box every year for her birthday. } \\ \text { Let } y \text { represent the number of years from now and } b \text { represent the total number } \\ \text { of lunch boxes in her collection. }\end{array} \] Use the function \( b=y+20 \) to find the value of \( b \) when \( y=1 \). \( b=\square \)

Solve: \( \frac{16^{x-1}}{4}=64 \)

Read the following description of a relationship: \[ \begin{array}{l}\text { A furniture company plans to have } 19 \text { employees at its corporate headquarters } \\ \text { and } 8 \text { employees at each store it opens. } \\ \text { Let } s \text { represent the number of stores and } m \text { represent the total number of } \\ \text { employees. }\end{array} \] Use the function \( m=8 s+19 \) to find the value of \( m \) when \( s=2 \). \( m=\square \)

Read the following description of a relationship: Tori uses 12 tomatoes to make each bowl of salad. Let \( s \) represent the number of bowls of salad and \( t \) represent the total number of tomatoes she uses. Use the function \( t=12 s \) to find the value of \( t \) when \( s=7 \).
