Answer:
their is a 50 50 chance
Step-by-step explanation:
write question properly bro
The equation is y=mx+b so u probably have to graph
Let y = daily rate
let x = number of people
let m = charge per person
let b = arbitrary cost
so, y=mx+b
150 = 20m + b
330 = 50m + b
30m = 180
m = 6
b = 30
so linear relationship : y = 6x+30
if x = 30
y = 180 + 30
y = 210
