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

205

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 + (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 + (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}`
