Question

! H E L P !

I have no idea, could you please answer them all I’d appreciate it.

Answer 1

The constant of proportionality is 5

For the first bar day: 1 cell phone sold: 5 (unit rate:5)

second bar day: 2 cell phones sold: 10 (unit rate:5)

third bar Day: 3 cell phones sold: 15 (unit rate: 5)

fourth bar day: 4 cell phones sold: 20 (unit rate 5)

Basically you divide the cell phones sold by the day or
`(rise)/(run)`

Hope this helped <3
