A) The equilibrium prices P1 and P2 for two goods satisfy the equations: 9P1 + P2 = 51
3P1 +4P2 = 39
Express this system in matrix form and hence find the values of P1 and P2 using inverse matrix.
b) If the market extends to 3 goods with prices P1, P2, and P3 which satisfy:
P1 +2P2 + 3P3 = 42
2P1 + P2 +4P3 = 47
P1 + 3P2 +4P3 = 57
Determine the equilibrium prices of three interdependent commodities using inverse matrix.

i can answer this question sweetie!

step-by-step explanation:

x -

median = 1.25

range = 12-14.5

interquartile = q12-q14.5

y -

median = 1

range = 15-17

interquartile = q15-q17

b

step-by-step explanation:

answer: first option i.e. 'a' is correct.

step-by-step explanation:

since we have given that

number of minutes to wrap a small gift box = 4 minutes

we need to find the number of gifts to be wrapped in 5 minutes

since there is a direct variation, as the number of minutes will increase with   number of gifts to be wrapped.

so, let the number of gifts to be wrapped in 5 minutes be x.

so, it becomes,

hence, first option 'a'   is correct.
