The cost of making a phone is $152. A store sells the phone for $281.20. Select all the expressions that could be used to find the percentage of markup for the phone.

The store is selling the phone by 185% of its value...

Step-by-step explanation:

You just gotta divide 281.20 (the value of the phone at the store), and divide it up by 152 (its original value). And multiply the result by 100 to get the percentage.

%

the answer is 96 degrees

step-by-step explanation:

you have to realize that a line equals 180 degrees

x = ± 6i

step-by-step explanation:

x^2 = -36

take the square root of each side

sqrt(x^2) = sqrt(-36)

we know sqrt(ab) = sqrt(a) sqrt(b)

x = ±sqrt(36) sqrt(-1)

we know that sqrt (-1) = i

x = ± 6i
