The amount of money college students spend each semester on textbooks is normally distributed with a mean of 195 and a standard deviation of 20. suppose you take a random sample of 100 college students from this population. there would be a 68% chance that the sample mean (x) amount spent on textbooks would be between?

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:

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%
