Anna gets paid $8.75/hour working as a barista at coffee break. her boss
pays her $9.00/hour for creating the weekly advertisement signs. she
works a total of 25 hours each week.
part a: let x represent the hours that anna works each week as a barista.
write a function h(x) to represent the amount of money that anna
eams working as a barista.
part b: write a function f(x) to represent the hours anna works creating
the signs.
part c: let s represent the number of hours that anna works creating the
signs. create a function g(s) to represent the money anna earns
creating the signs.
part d: find g(f( what does this composite function represent?

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!

i think it will be zero as slope has a formula of difference between initial and final distance divided by itz time interval
