You can put this solution on YOUR website!
y = a*b*x

y is the total amount spent per month

a is the number of times they go out to eat.

b is the average cost per meal.

x is the number of people.

If you have 4 people and they go out 2 times a month and the average cost per meal, then:

a = 2
b = 30
x = 4

y = a*b*x = 2*30*4 = 60*4 = 240

You can put this solution on YOUR website!
(cost/meal)*(meals/month) = (total cost)/(month)
30%2A4%2A2+=+Y
Also,
(number of people)*(times going out to eat/month) = number of meals/month
2x+=+8
X+=+4
when Y+=+240
Y+=+60X
I'm not sure if this is what's needed
