1. If there are 5,000 gallons of water at the start, how much is there at the end of the entire time period? What number sentence shows your reasoning?

2. What was the average rate of water flow per hour in the first 11 hours?

3. What was the average rate of flow of water per hour in the last 9.5hours?

4. At the end of the entire time period, what was the average rate of flow (in or out) per
hour?
I

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.
