Sagot :

Answer:

Step-by-step explanation:

Number of shells she had in the begining = 40

Number of shells collected in the morning and at noon = 6 + 3 = 9

Now the number of shell at the end = 40 + 9 = 49

Icreased shells = 49 - 40 = 90

[tex]\text{Percentage increase = $\dfrac{49- 40}{40}*100$}[/tex]

                                [tex]=\dfrac{9}{40}*100\\\\\\= 22.5 \ \%[/tex]
