Nana76 [90]

Answer:

Number of fruit flies after 14 days is equal to 1880.

Step-by-step explanation:

given,

fruit flies at the beginning of the experiment = 200 fruit flies

rate of increase of fruit flies = 5 per hour

to calculate the number of flies after 14 days.

time = 14 days = 14 × 24 = 336 hours

flies after 14 days = initial number of flies + rate of increase  × time

                             = 200 + 5 × 336

                             = 1880 fruit flies.

hence,Number of fruit flies after 14 days is equal to 1880.
