Neil started a stamp collection with 12 stamps. every week , he adds 4 more stamps to the collection. which function? f represents the relationship between the number of stamps (s) and the number of weeks (w)

Step-by-step explanation:

Let

s -----> the number of stamps

w ----> the number of weeks

we know that

The linear equation that represent this situation is

----> equation of the line into slope intercept form

where

the slope m is equal to

the y-intercept b is equal to ---> (the initial value)

the answer would be c:   ax + b = ax + c

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%
