The line through the center of dilation that contains points E and F, after dilation, ...

contains the points E and F.

Scenario 1

It is given that on Albert's favorite shoe website, the prices for a pair of the shoes range from $80 to $180 and the delivery fee is one-twentieth of the price of the basketball shoes.

From the above pieces of information we see that the minimum that Albert will have to spend is $80+\frac{1}{12}\times 80=80+6.67=86.67$ dollars.

Now, we know that Albert can spend a maximum of $105 including the delivery fee. Let the upper limit of the price of the shoe Albert can buy be $x$ . So, the upper limit of the domain can be found as:
