A bag contains 9 blue marbles and 1 green marble what is the probability of drawing a blue marble followed by a green marble without replacing the first marble before drawing the second marble

9/10 to draw a blue marble

then a 1/9 to draw a green marble

answer:   expression= p+p*d%

price reduction + sale price = $625

sale price: $p+$p*d%

where d% is the percentage of discount

step-by-step explanation:

original price = p

price went down by $150 price reduction $p*d%

sale price= $ 475

therefore the price before sale is: $625

and the expression that shows the price before sale is: p+p*d%
