Robby has a pitcher containing 2 3/4 gallons of lemonade, and he pours it into cups that each hold 1/8 gallon until the pitcher is empty. How many cups does he fill?

  22 cups

Step-by-step explanation:

Each gallon fills 8 cups, so Robby fills ...

  (2 3/4)×8 = 2×8 +3/4×8 = 16 +6 = 22 . . . cups

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.
