Answer:
3 for $8
Step-by-step explanation:
Firstly, 3 for $8 is much better than 5 for $8. Same for 12 for $24 being better than 14 for $24, because it's the same price for a different amount. Now we multiply 3 for $8 by 3, to get 9 for $24, which is better than 12 for $24, so the answer is 3 for $8

Answer:
168 = x
Step-by-step explanation:
mean = u=132
standard deviation =sigma = 20
z score =z=1.8
The formula is
z = (x-u)/ sigma
Substituting what we know
1.8 = (x-132)/20
Multiply by 20
1.8*20 = (x-132)/20 *20
36 = x-132
Add 132 to each side
36+132 = x-132+132
168 = x
