Answer: [tex]M = 50 + 7.50 h[/tex]
Step-by-step explanation:
As per the given scenario,
Total money Christina made = (Money she made in tips) + (Per hour wage ) x (Number of hours she work in one night) (i)
Let M is the total money she makes and h is the number of hours she works in one night.
Here, Money she made in tips = $ 50
Per hour wage = $7.50
So substitute all the values in (i), we get
[tex]M = 50 + 7.50 h[/tex]
Hence, the required function is [tex]M = 50 + 7.50 h[/tex].
