Answer:
x=4 y=12
Step-by-step explanation
the total amount spent was $12. Joylin bought 3 videos. 12/3=4 so x=4 and y=12
Answer with explanation:
y= Total Cost in Dollars to download videos from website
x= Number of videos Downloaded
Let the cost of downloading a video = $k
Total cost of downloading 3 videos =$ 12
⇒3 k =12
Dividing both sides by, 3
k=4
Cost of Downloading a Video = $ 4
So,the proportional relationship between y, the total cost in dollars of downloading videos from a website, and x, the number of videos downloaded in the form of equation written as:
→ y = k x
→y=4 x, replacing , k by 4 as cost of Downloading a video is $ 4.
is the equation written by Joylin.
