It wouldn’t be divided by, only because she’s not sharing it among 3 different people.
Instead I would write x - 3 because you’re taking away 3 candy bars.
Remember that the y-intercept is where the function has a value of
and the x-intercept is where the function has a value of
. Thus, to find the x-intercept and y-intercept, we can substitute these values into the equation and solve for the other variable.
<u>x-intercept</u>
Since the x-intecept has a y-value of 0, we can substitute this into the function and solve for
.



The x-value of the x-intercept is
and the y-value is 0, meaning that the x-intercept has coordinates
.
<u>y-intercept</u>
Since the y-intercept has a x-value of 0, we can substitute this into the equation and solve for
:


The y-value of the y-intercept is -3, meaning that the y-intercept of the function is
.
Christopher needs to create so that his time spent will be the same as his current time, the equation could be: 2.4x = 1.2x + 15
I got 20,737 but I could be wrong so I will attach my algorithm and work.
