The waitress and hostess at a restaurant share the tips at the end of every shift. between the two of them, they earn an average of $75 in tips. the waitress take $55 and the hostess takes $20. if they continue to earn money at this rate, how much will the waitress receive if they earn $300 at the end of their next shift?

thy get 55/75 and you want to know x/300

55/75 x X/300

 cross multiply 55 x 300 = 16500

 divide that by 75

16500/75 = 220

 x = 220

 they will get $220

step-by-step explanation:

we have

using a graphing tool

see the attached figure

this is a quadratic equation (vertical parabola) open up

the vertex is a > vertex

the domain of the function is all real > interval (-∞,∞)

the range of the function is the > [-6.125,∞)

the function has two x->   and

the function is increasing over the > (0.25,∞)

the function is decreasing over the > (-∞,0.25)
