Answer:
or ![y = \frac{50}{3} + 100](https://tex.z-dn.net/?f=y%20%3D%20%5Cfrac%7B50%7D%7B3%7D%20%2B%20100)
Step-by-step explanation:
The equation of a line is
, with
being the slope and
being the y-intercept.
We can see on the graph that the y-intercept, where the line crosses or touches the y-axis, is 100. So, our new equation is
.
Now we have to find the slope. Let's pick a point that's clearly on the graph. Perhaps (3, 150). And then we'll take the y-intercept point for convenience, (0, 100).
Then, we'll use
to find the slope.
Let's substitute in our points.
![\frac{150-100}{3-0}](https://tex.z-dn.net/?f=%5Cfrac%7B150-100%7D%7B3-0%7D)
Simplify.
![\frac{50}{3}](https://tex.z-dn.net/?f=%5Cfrac%7B50%7D%7B3%7D)
Now, we can leave the slope like that or turn it into a mixed number. As a mixed number, your slope is
.
We'll put that in our equation for a line and...bam!
or ![y = \frac{50}{3} + 100](https://tex.z-dn.net/?f=y%20%3D%20%5Cfrac%7B50%7D%7B3%7D%20%2B%20100)
Answer:
She spent 40 more dollars or to be exact 40.70 dollars more then aiden
Step-by-step explanation:
Aiden bought 60 candles.
0.37*60 is equal to $22.20
Aidens sister bought 170 candles at same price of $0.37
0.37*170=$62.90
Now subtract
$62.90-22.20=$40.70
She spent 40 more dollars or to be exact 40.70 dollars more then aiden
