Answer:
The total is $1250
Explanation:
Step one:
given data
The cost of a school banquet is $95
And an additional $15 for each person
Let the number of persons attending the banquet be x
and let the total expenses be y so the slope-intercept form is given as
[tex]y= 95+15x------------1[/tex]
Step two:
Now for x= 77, the total expenses would be
[tex]y= 95+15(77)\\\\y= 95+1155\\\\y=$1250[/tex]
