A / B
= 80 / 8
= 10
Therefore the answer is 10
Answer:
The correct answer is - 12.
Step-by-step explanation:
Given:
Total number of people = y = 39x+50
Total amount spent y = 518
Solution:
The equation for the number of people who attended the dinner
y = 39x+50
The cost of dinner is equally divided by number of people =
then, 518 = y
placing value, 518 = 39x+50
x = (518-50)/39
= 468/39
= 12
Then number of people attended the dinner = 12
The constant proportionality is whats left over
It is the first choice. All you have to do is isolate A from 2A so you would divide by 2 and get A=bh/2
If Carly had more DVDs than Rob then you would subtract her amount away from the total. 42-4=38
