Any number thats 8.5 or above
It is better for Gina to buy the individual boxes for $21.99 rather than to buy Each carton for $3.99
To find the total amount for the 1/2 gallons, you 1st round $3.99 to $4 then you multiply 4 by 6 to get 24. This means she pays a total of $24 for the 1/2 gallons.
The reason that you multiply 4 by 6 is because you'd need 6 1/2 gallons to make 30 servings

Answer:
There is no value of x to fit this requirement.
Step-by-step explanation:
The 2 perimeters in terms of x are:
4(x + 3) for the square and
2(x+1) + 2(x +4) for the rectangle
and these need to be equal so
we equate these 2 and solve for x:
4(x + 3) = 2(x+1) + 2(x +4)
4x + 12 = 2x + 2 + 2x + 8
4x + 12 = 4x + 10
4x - 4x = 10 - 12
0 = -2 which is of course absurd so there is no solution to this equation.
