John is redoing his dining room floor (12 ft by 10 ft) using wooden tiles. the square tiles are 8 inches long. john priced the tiles at several different places and found the cheapest price to be $1.50 each tile. john has saved $400 to buy the tiles. a) how many tiles will it take to cover the dining room floor? b) does john have enough tiles to buy the tiles?

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.
