A clothing store is having a sale in which everything is 10% off. A shirt's original price is $27. A customer uses a coupon for $5 off after the sale price. How much did the customer save? A. $3.92 B. $7.20 C. $7.70 D. $19.30

C. $7.70

Step-by-step explanation:

First, you have to calculate the 10% of the price and subtract that from the price to find the amount of the discount:

$27*10%=$2.7

Now, you can add the amount of the discount plus the coupon to find the amount that the customer saved:

$5+$2.7=$7.7

According to this, the answer is that the customer saved: C. $7.70

option: d is correct

step-by-step explanation:

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.
