X=9.3 is the answer to the question
D = 5.5p + 25
D: dollars
P: people attending
F(5)= 3.(5)+2=15+2=17
Another example: F(0)=3.(0)+2=0+2=2
You just replace the value in the two sides.
The equation to solve would be setting
60×- the m plus 75,the b set to 200 the maximum that's wanted to be used. the equation will look like this
200=60x+75
-75. -75
125=60x
125/60 60x/60
2.08=x
and since you cant round the time the answer will be left at 2
