The sticker warehouse sells rolls of stickers for $4.00 each. the average custiomer buys six rolls of stickers. the owner finds that for every $0.25 decrease in price , the average customer buys an additional roll.
a) with how many price reductions will the revenue per customer be $30?
b) what is the maximum predicted sales revenue per customer? with how many price reductions will this occur?

The sticker warehouse sells rolls of stickers for $4.00 each.

The average customer buys six rolls of stickers.

The owner finds that for every $0.25 decrease in price , the average customer buys an additional roll.

A:

We can find this by decreasing the price by $0.25, then multiply the number of rolls by the price, till we get $30.

We can see that there will be 4 price reductions.

B:

Here we can see that the sale revenue per customer is going down, so the answer is the highest value before this, which is $30.25. And there will be 6  reductions.

fa tha first one you gonna add y to both sides

it look like this

x-y+y=6+y

x=y+6

therefore your answer is

x =y+6

fa tha second one

you gonna flip tha equation

it gonna look like x-4y=y

then add 4 to both sides

it gonna look like tha

x-4 +4 =y +4

so therefore tha answer is x=y+4

step-by-step explanation:

y = 5x + 17

step-by-step explanation:

a perpendicular line will be the opposite reciprocal slope of the given equation.   the slope given is -1/5 so the opposite reciprocal is 5

find b:

7 = 5 (-2) + b

7 = -10 + b

17 = b

write equation

y = 5x + 17
