A certain laptop is really popular and sells for $199.99. Since sales are so good, the store raises the price by 13%. What is the cost after the markup? Explain how you do it.

$255.98.

Step-by-step explanation:

The original price is 199.99.

If the store raises the price by 13%, then we must simplify 13% into decimal form.

13% = 13/100 = .13.

199.99 x .13 = 25.99

If they raised the price by 13%, then we are adding the original price to the 13% they added.

199.99 + 25.99 = 225.98

The price after raised by 13% is $255.98.

9.55 degrees.

step-by-step explanation:

the given angle is

1 cycle is equal to 2π radians. so 4π will be equal to two cycles.

5.166667π-4π = 1.166667π

hence, this angle goes a little more than negative x axis.

1.166667π-π= 0.166667π

hence, the reference angle is 0.166667π radians.

1 radian = 57.2958 degrees

now, in degrees, this should be equals to 9.55 degrees.
