The local furniture store pays $300 for a dining room table and sells it with a 40% markup. What is the selling price of the dining room table? \ Selling Price = ?, Cost + Markup = ?

$420

Step-by-step explanation:

Cost to the furniture store: $300

Markup: 40%

40% * $300 = $120

The markup is $120

Selling price = cost + markup = $300 + $120 = $420

$420

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.
