QA=96-2PA_3PB

QB=30-25PA+0.32Y
Given that PA=2,PB=4,Y=1000

To find the values of QA and QB, you can substitute the given values of PA, PB, and Y into the respective equations.

Given:
PA = 2,
PB = 4,
Y = 1000

Equation 1: QA = 96 - 2PA - 3PB
Equation 2: QB = 30 - 25PA + 0.32Y

Substituting the values:

For Equation 1:
QA = 96 - 2 * 2 - 3 * 4
QA = 96 - 4 - 12
QA = 96 - 16
QA = 80

For Equation 2:
QB = 30 - 25 * 2 + 0.32 * 1000
QB = 30 - 50 + 320
QB = 300 + 320
QB = 620

Therefore, QA = 80 and QB = 620 when PA = 2, PB = 4, and Y = 1000.
