Answer:
Part 1) The linear equation is
Part 2) if he has 90 protein bars left, then 52.5 days have passed
Step-by-step explanation:
we know that
The linear equation in slope intercept form is equal to
where
y is the number of protein bars left
x is the number of days
m is the slope or unit rate
b is the y-intercept or initial value
In this problem we have
The slope is equal to
----> is negative because is a decreasing function
substitute
---> linear equation that represent this situation
If he has 90 protein bars left
so
For y=90
substitute in the linear equation and solve for x
therefore
if he has 90 protein bars left, then 52.5 days have passed
