We know that

The variable x must be either degree zero or degree 1 and the variable y must be 1st degree in order to be a linear function.

case A) x=5
the variable x is first degree but variable y is zero degree---> is not a linear  function

case B) y=2x
the variable x is first degree and  variable y is first degree----------> is a linear  function

case C) y=2x²
the variable x is second degree and  variable y is first degree----------> is not a linear  function

case D) y=x³
the variable x is third  degree and  variable y is first degree----------> is not a linear  function

 the answer is
the option  B) y=2x is a  linear function

A bike store sells scooters at a 54% markup. If the store bought each scooter for $29.25, what is the resale price to the neares
7nadin3 [17]

The purchasing price of the store = $29.25.

They want to resale it at 54% markup of the purchasing price.

54% of 29.25 = 0.54 × 29.25.

On multiplying 0.54 and 29.25, we get 15.795.

Resale price = The purchasing price + Markup

                      = 29.25 + 15.795.

On adding 29.25 and 15.795, we get 45.045.

We can round it to 45 to the nearest dollar.

<h3>Therefore, the resale price to the nearest dollar is $45.</h3>
