It has the following utility function: u(x, y)equals=10upper x squaredx2y where x is her consumption of blu-ray disks with a price of $2525 and y is her consumption of dvds with a price of $55. she has $21002100 with which to spend on the two goods. determine the number of blu-ray disks and dvds that will maximize carycary's utility.

it is x equals 3   plese mark me really need it

step-by-step explanation:

constant of proportionality = 3 and the equation is c = 3p.

step-by-step explanation:

c = kp   where c = amount of caffeine in mg., p = oz of pepsi and k is the constant of proportionality.

substituting the values given:

24 = 8k

k = 3.

the same value of k will be obtained if we substitute the other given values.

the answer would be 0.54
