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.

Sorry this isn't that helpful... I hope someone helps you soon.
It’s the second one, cuz that’s the correct formula and equation
Answer:
<h2>12.1% profit</h2>
Step-by-step explanation:
Given data
total eraser= 87
cost =$3 each
Total cost of eraser= 87*3= $261
she sold 63 at $3.5
1. sales made for the 63= $220.5
2 sale made for the remaining= 87-63=24
24*3=$72
Total sales made = 220.5+72=$292.5
her profit= sales-cost
profit= 292.5-261=$31.5
therefore the percent profit is
=31.5/261*100
=0.12*100
=12.1%
