The total cost for a bucket of popcorn and 4 movie tickets is $56. The total cost for the same size bucket of popcorn and 6 movie tickets is $80. Which equation represents the relationship between y, the total cost of the popcorn and movie tickets, and x, the number of movie tickets that are purchased?
what lesson is this.
linear equations
y = popcorn and x = ticket y + 4x = 56 y + 6x = 80 these are the equations you will use...do you prefer substitution or elimination ?
oh...read the q wrong....do you have answer choices ?
yes the answer choices will be great can you show them
y=12x+8 y=12x+24 y=4x+6 y=14x+28
(4,56)...x1 = 4 and y1 = 56 (6,80)...x2 = 6 and y2 = 80 slope(m) = (y2 - y1) / (x2 - x1) slope(m) = (80 - 56) / (6 - 4) slope(m) = 24/2 slope(m) = 12 y = mx + b slope(m) = 12 (4,56)...x = 4 and y = 56 56 = 12(4) + b 56 = 48 + b 56 - 48 = b 8 = b y = 12x + 8 <==answer
y= 12x + 8 is the answer
