Karen paid $1.20 for 6 pencils and 4 erasers at the school store. 6x+4y=1.20

Trey paid $1.10 for 8 pencils and 2 erasers at the school store.
8x+2y=1.10

How much does an
eraser cost?

i would be happy to . most people on would also love to i'm sure. if you just want someone who has done algebra before and want a little more personal relationship than just begging strangers for , i can certainly be of service. i do have college myself so i might not be 24/7.

step-by-step explanation:

just add the numbers then put the negative sign on it

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

y=20x

: )

hope this
