Which expression can be used to find the price of a $400 telescope after a 32% markup? Select all that apply. A. 400 • 0.32 B. 4
irina1246 [14]

Answer:  Option 'C' is correct.

Step-by-step explanation:

Since we have given that

Original price of  a telescope = $400

Mark up percent = 32%

So, Price after mark-up is given by

400\times \frac{100+32}{100}\\\\=400\times \frac{132}{100}\\\\=400\times 1.32\\\\=\$528

Hence, Option 'C' is correct.

The order pair below is a solution to which equation (24,6)
Illusion [34]
It would be much easier for me to help you pick the correct equation
if you would let me see the list of choices.

Since I can't see any of the choices, I'll just make up a few equations
that have the ordered pair  (24, 6)  as a solution:

         Y  =  0.25 x

         Y  =  x  -  18

         Y  =  0.5 x  -  6

         Y  =  0.1 x  +  3.6
