Sonya buys a baseball jersey for her brother on sale for 20% off. If the price she paid was \$6 lower than the regular price, what was the original price of the jersey?

The original price of the jersey is \$ 30

What is Percentage?

A percentage is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign, %

Given data ,

Let the original price of the jersey be = \$ x

The percentage discount on the original price = 20 %

The difference between the original price and the discounted price = \$ 6

So ,

By the percentage equation ,

Percentage discount on the original price = difference between the original price and the discounted price

And ,

( 20 / 100 ) of original price = \$ 6

On simplifying the equation , we get

( 20/100 ) x = 6

( 1/5 ) x = 6

Multiply by 5 on both sides , we get

x = 5 x 6

x = \$ 30

So , the original price of the jersey is \$ 30 and the discounted price is \$ 24

Hence , the original price of the jersey is \$ 30

I need help on question 6.

Step-by-step explanation:

First you now that ABD+DBC=180 degrees

Subsitute so you get: (5x+10)+(2x-5)=180

Solve:

(5x+10)+(2x-5)=180

=> 7x+5=180

=> 7x=175

=> x= 25

Plug in 25 :

ABD= 5*25+10=135
