Question

1. a magician charges a $30 fee to cover travel and expenses, plus $19.99 per hour. write an equation to represent the relationship between h, the number of hours, and t, the total charge for the magician.

Explanation:

Step1: Identify fixed and variable costs

The fixed fee is $30 (doesn't change with hours). The variable cost is $19.99 per hour, so for \( h \) hours, it's \( 19.99h \).

Step2: Formulate total charge

Total charge \( t \) is fixed fee plus variable cost. So \( t = 30 + 19.99h \).

Answer:

\( t = 30 + 19.99h \)
