Question 285597
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
