Answer:
Bernice would need 6 days assuming that everything remains constant to make $2430.
Step-by-step explanation:
Assuming she sells every single seashell every day.
First, find the total amount she makes per day by multiply the amount she sells them for ($3) with the total amount of sea shells she sells each day ($135):
135 x 3 = $405
Bernice makes $405 each day.
Now, to solve for the amount of days, divide the total amount she wants to make ($2430) with the amount she makes per day ($405):
2430/405 = 6
Bernice would need 6 days assuming that everything remains constant to make $2430.

Most people use the decomposition method but i dont know how to do that so i use the Joes method a method similar to decomp. but easier.

Find gcf: None
complet trinomial: 18n^2+57-10
find the product=10(18)
=-180
find the sum =57
-3 and 60 goes into both meaning if you multiply 3 and60 you get -180 and if you add them you get 57.
so (n-3)(n+60)
divide by a in this case it 18
so (n<u>-3</u>)(n+<u>60</u>)
18 18
do not divide. treat it like a fraction so you reduce it to lowest terms
(n<u>-3</u>)(n<u>-3)
</u> 18 10
<u /> at this point its reduced to lowest terms so now you take the deniminator and move it beside the "n"
=(18n-3)(10n-3)
therefore your answer is (18n-3)(10n-3)
I hoped this helped :)
