Step-by-step equation for a B & C Must show all work .work on a piece of paper send a piece of paper thank you. Whoever gets it right gets extra points.

Hey there!

a.) 1 inch

beginning = 2; end = 3; difference of 1

b.) December, because the length was, let's say, 2, then it went down 1 (so we're at 1), then went up 3 (4), then went down

c.) in December

Hope it helps, have a great day!

Step-by-step explanation:

a.total change in my hair =2-1+3-4+3=3inches

b.my hair is longer on December because the length of my hair is 3inches but 2inches in January.

c.my hair is longest as on December because the length of my hair is longer than on other month.

step-by-step explanation:

let's assume

number of candles set =x

price of of x candles =p(x)

we are given

a candle maker prices one set of scented candles at $10 and sells an average of 200 sets each week

so, we get point as (200,10)

he finds that when he reduces the price by $1, he then sells 50 more candle sets each week

so, we can find slope

now, we can use point slope form of line

now, we can plug values

we can use point

and find b

now, we can plug it back

and we get

now, we can find revenue

we know that

revenue = price*quantity

so, we get
