Question

3. For babysitting, Nicole charges a flat fee of $3, plus $5 per hour. Write an equation

for the cost, C, after h hours of babysitting. What do you think the slope and the y-
intercept represent? How much money will she make if she baby-sits 5 hours? Graph

Answer 1

The cost, C, after h hours of babysitting is $3 + 5h. The slope of this equation is 5, which represents the amount of money Nicole earns per hour of babysitting. The y-intercept of this equation is 3, which represents the flat fee that Nicole charges for babysitting. If Nicole baby-sits for 5 hours, she will earn 3 + 5(5) = $28.
