Question

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. How much money
will she make if she baby-sits 5 hours? *

Answer 1

The equation is C = 5h + 3

After 5 hours, Nicole will make $28.

Explanation:

The equation is C = 5h + 3 because the flat fee of $3 represents the y-intercept of the equation and the $5 per hour is the slope. Therefore, since in the equation y = mx + b, m is the slope and b is the y-intercept, you just substitute m for 5 and b for 3. Then, to find how much money Nicole will make in 5 hours, you just substitute the value, h = 5 into the equation that we arrived at. Thus, C = 5*5 + 3 which is 25 + 3 which is 28.

Hope this helps :)
