the dinner. If a family spent $518, how many people attended the dinner?

Answer 1

The correct answer is - 12.

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

x = (518-50)/39

= 468/39

= 12

Then number of people attended the dinner = 12
