QuestionLavania starts with 20 fruit flies. After 6 days, she has $5 \times 20 + 9$ . Find this population after 6 days.

Studdy Solution

STEP 1

Assumptions1. The initial population of fruit flies is20. . After6 days, the population is nine more than five times the initial population.

STEP 2

We can write an expression for the population of fruit flies observed after6 days. According to the problem, this is nine more than five times the initial population. In mathematical terms, this can be written as $Population_{6\,days} =5 \\times Initial\, population +9$

STEP 3

Now, we can substitute the initial population into the expression. The initial population is given as20.
$Population_{6\,days} =5 \\times20 +9$

STEP 4

First, perform the multiplication operation.
$Population_{6\,days} =100 +9$

STEP 5

Finally, add the two numbers to find the population of fruit flies after days.
$Population_{\,days} =100 +9 =109$ avania observed109 fruit flies after days.
