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.

Answer:
Y = 15x + 30 and 8 hours
Step-by-step explanation:
She gets $15 per hour so her income is based on her hours, but we don't know what that is yet so, 15x.
She gets a solid $30 every week that is straight forward
To solve the function
150 = 15x + 30
subtract 30 from both sides
120 = 15x
divide 15 from both sides
8 = x
or
x = 8
You got this :)
C...to show this, interchange letters: x = (y+1)/(y-1)xy-x = y + 1xy - y) = x + 1y(x-1) = x+1y = (x+1)/(x-1) ⇐ this is f-1(x) and it's identical to f(x). Note: <span>the equal sign is missing in the definitions of the functions c. & d.</span>
