Write a function rule for the table.

Alright, so in the table, x is the input, or the hours worked. The pay, or the output, is our y value.

This shows for every 2 hours worked, we get 15 dollars.

Let's write it out

2x=y

y=15

x=1 hour

The x is hours and the y is dollars.

A function rule is written as a ratio.

So we will compare hours to minutes.

Our function is 2:15

2:15

tickets for the harlem globetrotters

show at michigan state university in

2010 cost $16, $23, or, for vip seats, $40.

total revenue = 16x + 23y + 40z

if 9 times as many $16 tickets were sold

as vip tickets,

x = 9z => x – 9z = 0, if 9 times as many $16 tickets were sold

as vip tickets,

x = 9z => x – 9z = 0, sales of all three kinds of tickets would

total $46,575.

16x + 23y + 40z = 46575, how many of each kind of ticket would

have been sold?

solve for x, y and z

x − 9z = 0

x − y − z = 55

16x + 23y + 40z = 46575

x = 1170

y = 985

z = 130

welcome!
