Tanya and Adeola multiplied 399 by 25,. Tanya's awnser was 2793, and Adeola's was 9975, Whose awnser was reasonable, explain, and also explain the other studens awnser (NO CALCULATORS, AND IF U NEED ONE MAKE IT LOOK LIKE U DIDNT USE ONE)

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.
