Answer:
y = 50x +150
Step-by-step explanation:
We will use the slope intercept form
y = mx+b where m is the slope and b is the y intercept
The slope is how much it changes per day
m = 50
The y intercept is how much it starts with at day 0
b = 200
y = 50(x-1)+200 where x is the number of days
Since it starts at day 1, we need to make x be day 0, so we subtract 1
y = 50x -50 +200
y = 50x +150
