Bill's age = x
Eya's age = 3x - 5
Eya is 28
28 = 3x - 5
28 (+5) = 3x -5 (+5)

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.
B)1,131.20 would be the answer. 1010x0.14=141.4x8=B
