Sophia bought items from the bake sale at school. She bought a sea salt caramel brownie for $1.94 and a dozen chocolate chunk cookies. The total cost before tax was $9.98. How much was each cookie?

Each cookie is $0.67

Step-by-step explanation:

Equation:

1.94 + 12c = 9.98

12c = 8.04

c = 8.04/12

c = 0.67

1 cookie was $ 0.67

step-by-step explanation:   divide the numerator by the denominator to get the decimal

it would still be 193

if divide by 100 then 1.93

i am not sure

center (1,3) with radius 6

step-by-step explanation:

we must complete the square to find the center and radius of the circle.

first make sure the x and y squared terms have 1 as their coefficients. we also make sure x and y terms together.

we now create space between the x and y terms with parenthesis.

we complete the square by taking the middle terms -2x and the -6y - divide each and square them.

we add the squares to both sides.

simplify.

and write the quadratics in factored form.

the center is (h,k) or (1,3). the radius is the square root of 36 which is 6.
