Luz’ family went out to breakfast on saturday. the bill was $38.50 and the family wanted to leave a 20 percent tip for the server. below is luz’s calculation.

$38.50(0.02) = $0.77

did luz calculate the gratuity correctly?

a) no, she should have multiplied by 2.
b) no, she should have multiplied by 0.2.
c) no, she should have divided by 2.
d) yes, the tip is correct.

No. It would be B because she multiplied by 0.02 which is 1 percent and the tip is 20 percent. 0.2 is 20 percent, so it is B

c.

step-by-step explanation:

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.
