Sally works in a cell phone store, she is paid a weekly salary of 80 dollars plus 5.25 dollars for each phone she sells. What equation can be used to find her total weekly income?

y = 85.25x

y=80x + 5.25

y = 5.25 + 80

Not here​

Let

x ----> each phone she sells

y ----> total weekly income

so

we have that

y=5.25x+80

because

the slope is m=$5.25 per each phone she sells

and the initial value or y-intercept is b=$80
