Higher order thinking see guy's work.
is his answer correct? what mistake did he make?
8,265 - 7,145
= (8,265 - 55) (7,145 + 55)
= 8,210 - 7,200
= 1,010

answer. d.289 hope that

for this case we must apply distributive property to the following expression:

the distributive property states that:

then, when applying the property we have to multiply the -2 for each term within the parenthesis:

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

he has 140 chickens because he has 10 times more chickens than ducks and he has 14 ducks so 14*10=140
