Answer:
The cell population would be:
1 hour? 252.25
4 hours? 259
11 hours? 274.75
Explanation:
The equation to find the cell population after x hours would be equal to the amount at which the population started at plus the expedition rate per hour for the number of hours:
y=250+2.25x, where:
y is the total cell population
x is the number of hours
Now, you can use the formula to find the answers:
-1 hour
y=250+2.25(1)
y=250+2.25
y=252.25
-4 hours:
y=250+2.25(4)
y=250+9
y=259
-11 hours:
y=250+2.25(11)
y=250+24.75
y=274.75
