Answer:
A manufacturer sells widgets for $3.25 each
They charge a flat shipping rate on all orders. An order of 15 widgets costs $53.75
Step-by-step explanation:
we are given the linear relationship between the cost of an order of widgets and the number of widgets ordered
[tex]y-53.75=3.25(x-15)[/tex]
where
y is the cost of an order of widgets
x is the number of widgets ordered
now, we can compare it with point slope form of line
[tex]y-y_1=m(x-x_1)[/tex]
we can find m ,x1,y1
[tex]m=3.25[/tex]
[tex]x_1=15,y_1=53.75[/tex]
we know that slope is rate of change
so, we get
charge of one widget is $3.25
number of widget =15 whose costs is $53.75
so,
A manufacturer sells widgets for $3.25 each
They charge a flat shipping rate on all orders. An order of 15 widgets costs $53.75
