Romona works in a clothing store where she earns a base salary of $140 per day plus 14% of her daily sales. she sold $600 in clothing on saturday and $1,200 in clothing on sunday. how much did she earn over the two days? explain.

here's what the equation would look like:

2(140) + 0.14(1200 + 600)

280 + 0.14(1800)

multiply:

280 + 252 = 532

she earned $532 in two days.

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.
