Answer:

2; 10

Step-by-step explanation:

12/2 = 6

(x+6)^{2} = x^{2} +12x + 36

   x^{2} +12x + 20

-   x^{2}<u> +12x + 36</u>

    0 + 0  - 16

(x+6)^{2} - 16 = 0

(x+6)^{2} = 16

x + 6 = \sqrt{16}

x = -4 + 6 = <u>2</u>

x = 4 + 6 = <u>10</u>

Joel sells ice cream cones at the county fair. He has to rent the equipment for $28 and spent $.33 on a gradients for each accou
spin [16.1K]
Rental - $28
Ingredients- $33
Total $61.00

At $1.30 each you can guesstimate he'd have to sell almost 60 cones to break even.
OR
You can divide 1.30 into $61.00 for about 47 cones to break even. (I rounded up)

To make a profit he would either need to sell double that amount or he could raise the cost of his cone to $2.00 & make profit sooner.
