Question

A cell population starts at 250 and is increasing at an expedition rate of 2.25 each hour. What will the cell population be after 1 hour? 4 hours? 11 hours?

Answer 1

Answer:

The cell population would be:

1 hour? 252.25

4 hours? 259

11 hours? 274.75

Step-by-step 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
