Answer
a) Meal cost | Money remaining
15 | 37.75
21 | 30.85
24 | 27.4
30 | 20.50
b) m=55-1.15c
Work Step by Step
We can find the equation m=55-1.15c because the person starts with 55 dollars and that becomes the y-intercept and since a 15% tax is being charged, that 15% becomes the slope as -1.15 because that is being subtracted from the total money which is 55.
We can find the table by plugging in the values in the function rule.
m=55-1.15c (plug in 15 dollars)
m=55-1.15(15)
m=55-17.25
m=37.75
This gives you the table values of (15 , 37.75)
