Max opened a new bag of birdseed and filled 4 bird feeders. She put 1,600 grams of birdseed into each feeder. There were 2,600 grams of birdseed left in the bag. What was the mass of the bag of birdseed in kilograms before Max opened it? God bless who ever answers.

20 points!!

option c) graph of line going through 1, 4 and 3, 10

step-by-step explanation:

let y equal to margo's coin collection

let x equal to number of years

at the begining x=0, y=1 → point=(x,y)→point=(0,1)

she adds 3 coins per year, then y=1+3x

at x=1, y=1+3(1)=1+3→y=4→point=(x,y)→point=(1,4)

at x=3, y=1+3(3)=1+9→y=10→point=(x,y)→point=(3,10)

the graph of line going through (1, 4) and (3, 10), then the option c is the correct.
