Bob and alice have a mortgage for $73,280. if the mortgage is set at 7 percent for 30 years, how much is their monthly payment if their rate is 6.75 per 1,000?

a) $494.64
b) $91,647
c) $243.64
d) $473.34

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%

but there’s no any figure there!
