Hi!
To solve this problem you can set up a proportion (I like doing it this way) or you can just do:
First deal:
(24/3)*5 = 40 dollars
Second deal:
(24/4)*6 = 36 dollars
Finding money saved:
40-36 =4
They will save 4 dollars buying the second 4 for 6 dollars deal!
It's c. the only way he can compare both is by calculating both groups' mean and comparing it. Randomizing wont work because it is mixing both protein bar users and non-protein bar players.
Answer:
50 = p + 42
Step-by-step explanation:
The unknown part of this equation is the variable p, the number of people that left. So you want to add p to 42 and that will give you the total number of football players, which is 50. In order to get p, you need to get it by itself and make it equal something. Subtract 42 from both sides and you are stuck with 50-42 = p
p = 8
