Answer:
Step-by-step explanation:
12 + 4b = 72
Subtract 12 on both sides
4b = 60
b = 15
Lets make a proportion with the information we know. For every 1000, 8 of tax is paid.
8/1000
Then, use the rest of the information to make another proportion. We don’t know how much the tax is, so let’s call it x.
x/150000
Set the equations equal to each other
8/1000=x/150000
Cross multiply
1000x=1200000
Divide by 1000 on both sides
x=1200
Answer:
$290
Step-by-step explanation:
We are told that 1 out of 5 buyers change to a more expensive sofa than the one in the sale advertisement.
Now we are told that the advertised sofa is $250 and the more expensive sofa is $450.
Thus;
P(x) for expensive sofa = 1/5
P(x) for sofa in sale advertisement = 4/5
Thus, expected value is;
E(X) = (1/5)450 + (4/5)250
E(x) = 90 + 200
E(x) = $290
