This is basically a part of PEMDAS.

First, you must do the parenthesis part, meaning to find the answer inside the parenthesis first.

Subtract 13.5–4.5 to get rid of the parenthesis. You get 9.

Now, finish the equation off: 5·9 (five times nine). You end up with 45.

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.
