Answer:

C) 125°

Step-by-step explanation:

Supplementary angles add to 180 degrees. Complementary angles add to 90

An angle's complement is 35°.

35+x =90

Subtract 35 from each side

35 -35+x = 90-35

x = 55

We want to find the supplement of this angle

55+y = 180

Subtract 55 from each side

55-55+y = 180-55

y= 125

The angle is 55 so its supplement is 125

4) If you bought a jersey at 30% off and paid $205.50, how much money did you save?

NemiM [27]

Answer:

$267.15‬

Step-by-step explanation:

The way my math teacher showed me to do it is take the price you paid and multiply it by 1.x (x being the amount of the discount).

In doing that, $205.50 multiplied by 1.30 is $267.15‬ and the original price of the jersey.

Hope this helps :)

Given details :

The selling price of a chandelier is $899
The profit gained js 45%

To find :

The cost price / Wholesale price

Solution :

We know that CP is ,

$\sf\implies\:CP\:=\:\dfrac{100}{100\:+\:P\%}\:\times\:SP$

Put the values in the formula ,

$\sf\implies\:CP\:=\:\dfrac{100}{100\:+\:45\%}\:\times\:899$

$\sf\implies\:CP\:=\:\dfrac{100}{145}\:\times\:899$

Simplify 899 with 145 that gives us 6.2

$\sf\implies\::\:CP\:=\:100\:\times\:6.2$

CP = $620
