A computer game usually sells for $40. Niko bought it when it went on sale for 25% off. The sales tax was 6%. How much did Niko pay for the game?

$31.80

Step-by-step explanation:

First, find the sale price.

Normally you pay for 100% of the price. Since it is 25% off, you only pay for 75% of the price. (100%-25%=75%)

Therefore, we can multiply 75% and $40

75% * $40

Convert 75% to a decimal by dividing 75 by 100 or moving the decimal place 2 spots to the left.

75/100=0.75

75.0 --> 7.5 --> 0.75

0.75* $40

Multiply

$30

Now, find the price with tax.

You have to pay for 100% of the price, plus an additional 6% for the tax. Therefore, you are actually paying for 106% of the price (100% + 6% = 106%)

Therefore, we can multiply 106% and $30

106% * $30

Convert 106% to a decimal by dividing 106 by 100 or moving the decimal place 2 spots to the left.

106/100=1.06

106.0 --> 10.6 --> 1.06

1.06 * $30

Multiply

$31.8

Niko paid $31.80 for the game.

answer: option a.

step-by-step explanation:

you know that the quadrilateral opqr ( a four sided figure) is inscribed in circle. this means that all its vertices are on the circle.

then, by definition, the opposite angles of the quadrilateral are supplementary, this means that the sum of their measures is 180 degrees.

you can observe in the figure that the angles ∠opq   and the angle ∠orq   are opposite, therefore:

then, can be used to d to calculate the measure of ∠opq
