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
