Question

Rewrite the following and with the rate of change , how much is the price increasing each hour?

A babysitter charges a 55 flat booking fee plus 55 for every hour she works, so the total pay y (in
dollars) after x hours is y = 5 + 5x. The graph starts at $5 when x = 0 (the booking fee) and rises $5 for
each additional hour, reaching $40 after 7 hours. So, this graph models shows how total pay increases linearly with time worked and can be used to predict earnings for any number of hours.

Answer 1

Corrected and rewritten:

A babysitter charges a $5 flat booking fee plus $5 for every hour she works. The total pay y (in dollars) after x hours is
y = 5 + 5x.
The graph starts at y = 5 when x = 0 (the booking fee) and increases by $5 for each additional hour, reaching $40 after 7 hours.

Rate of change: 5 dollars per hour (the price increases $5 each hour).
