unit cost of producing and distributing a penny was 1.21¢. what percent of the
value of a penny is this cost? what can you conclude about the cost of making
pennies?
• how can a model you to visualize the problem?
• how can you use a proportion or the percent equation to solve the problem?

ratio is 2 : 9

the answer is three

13.5 : 3

explanation:

step-by-step explanation:

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%

i believe it’s 165 because if u add 137 and 58 u get 195 and then subtract that from 360 and there’s ur answer
