A store pays $10 for a blanket, and the markup is 115%. A customer will also pay a 5 1/2% sales tax. What will be the total cost
Naddik [55]
Firstly, we need to find the price of the blanket/bracelet after the 115% increase.
     $10 x 1.15 = $15.20

Now for the 5.5% sales tax, which is applied the the new value of $15.20
     $15.20 x 0.055 = 0.83
     $15.20 + $0.83 = $16.03

The final cost for the blanket/bracelet is %16.03

Find the center and radius of the circle (x+3)^2+(y-1)^2=81
sasho [114]

The equation of a circle is written as ( x-h)^2 + (y-k)^2 = r^2

h and k is the center point of the circle and r is the radius.

In the given equation (x+3)^2 + (y-1)^2 = 81

h = -3

k = 1

r^2 = 81

Take the square root of both sides:

r = 9

The center is (-3,1) and the radius is 9

Problem 3
stich3 [128]
In the step after -6x+10=4x+20, he moved the terms incorrectly. you have to add 6x to both sides so it would be 10=4x+6x+20 which simplifies to 10=10x+20. subtract 20 from both sides to get -10=10x. divide both sides by 10. the answer is x=-1
