Miguel decided to buy a cell phone for $150. it is currently on sale for 10% off. when he got to the counter, he got an additional 10% off. what is the final cost for the cell phone?

(use x as your variable for your equation )

The final cost price of the cellphone is  $121.5

Step-by-step explanation:

The marked price of the cell phone = $150

Now, sale percentage on the marked price = 10%

Now, 10 % of 150 =

⇒The sale discount on the marked price = $15

So, the  selling price of cellphone = Marked Price - Sale discount

                                                        = $150  - $15  = $135

Now, the second discount offered on $135 is 10%

10 % of 130 =

⇒The additional sale discount on the selling price = $13.5

So, the final cost of cellphone = Selling Price - Additional Sale discount

                                                        = $135  - $13.5  = $121.5

Hence, the final cost price of the cellphone is  $121.5

f(x) is the value of the function. b is the value of the function when x equals zero or the y-coordinate of the point where the line crosses the y-axis in the coordinate plane.
