Step-by-step explanation:
The possible answers are not present
No. of People Cost
1 9.50
2 19.00
3 28.50
4 38.00
etc.
If we divide the cost in each row by the number of people in that row, we always have the proportion (ratio) of 9.50 / 1
9 = 4
18 = 8
27 = 12
36 = 16
45 = 20
First thing to do is solve the given equation for v
-11v-7 = 4
-11v = 4+7
-11v = 11
v = 11/(-11)
v = -1
Once we know this, we can use it to compute the following
7v-10 = 7*(-1) - 10 = -7 - 10 = -17
--------------------------------
Answer: -17
