10. examine the following solution to a linear equation. do you see a mistake? identify the first line of the solution that is incorrect (if any).

original equation: 30x = 23(1 + 3) + 12x + 22

solution:
11. examine the following solution to a linear equation. do you see a mistake? identify the first line of the solution that is incorrect (if any).

original equation: 15x + 12 – 8x = -3 + 7x - 7

solution:

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%

multiply then divide

step-by-step explanation:

change of stock price/initial stock price on friday * total stock value = change of stock value

0.89/73.73 *x = 42.72

x=3539.04 = total stock value at initial stock price on friday .

total stock value at initial stock price on friday/ initial stock price on friday = number of shares

3539.04/73.73 = 48 shares

they own 48 shares of this stock
