A) Just multiply each number of the chart by three. 1 x 3 = 3, 3 x 3 = 9, 5 x 3 = 15, and 6 x 3 = 18.
B) Since each rose is $3, your equation can be y=3x. X would equal the number of roses and y would equal the cost of the roses
C) Because each rose is $3, you would multiply 20 by 3. Therefore, 20 x 3 = 60
