Question

1. The number of fruit flies in a jar is 624 and growing at a rate of 4% every day. How many fruit flies will there be in 8 days? Enter your answer, rounded to the nearest whole number, in the box

Answer 1

Answer:

205

Step-by-step explanation:

Multiply Principle(642) by rate(0.04) and by time (8)=205

Answer 2

The Number of Fruit Flies in the Jar is given by the Formula :

✿  $\mathsf{Number\;of\;Fruit\;Flies = (Initial\;Number\;of\;Fruit\;Flies)(1 + \frac{Rate}{100})^n}$

Where : n is the Number of Days

Given : Initial Number of Fruit Flies in the Jar = 624

Given : Rate = 4%

Given : Total Number of Days = 8

$\mathsf{\implies Number\;of\;Fruit\;Flies = (624)(1 + \frac{4}{100})^8}$

$\mathsf{\implies Number\;of\;Fruit\;Flies = (624)(1 + 0.04)^8}$

$\mathsf{\implies Number\;of\;Fruit\;Flies = (624)(1.04)^8}$

$\mathsf{\implies Number\;of\;Fruit\;Flies = 854}$
