The cross-price of elasticity of demand for chocolate syrup with respect to the price of milk would be :
e = % ΔQ chocolate syrup / %ΔP of milk
e = -4% / 2%
e = -2 %
45/480=9/96=3/32
the answer is 3/32
Step-by-step explanation:
x/6-1=1/3(9-3x)
3(x-1) = 6(9-3x)
3x-3 = 54 - 18x
3x+18x=54+3
21x=57
X=57/21
R1t+t/2.5=1, we are told it takes both 1.5 hours so
1.5r+0.6=1
1.5r=0.4
r=4/15
So for this other pipe to fill the pool by itself...
4t/15=1
4t=15
t=15/4
t=3.75 hours
check..
4t/15+t/2.5=1
(4t+6t)/15=1
10t=15
t=15/10
t=3/2
t=1.5 hours, correct (for both pipes filling the pool)
