The supervisor of a community garden project organizes volunteers to dig out weeds. the more people they have, the more weeds get pulled. the results are better than one might think. although one person will pull only two bags a day, two people will pull five bags a day, and three people will pull eight bags a day.
the garden must be cleared of winter weeds. the supervisor estimates that there are 30 bags' worth of weeds to be pulled. how many volunteers are needed to get the job done in a day?

66answer:

step-by-step explanation:

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.

step-by-step explanation:

the answer is 128
