The concession stand at the high school football stadium south hot dogs and hamburgers to raise money for the high school athletic programs each hotdog sold earns the program's $0.50 annie chamber sold earns $0.75 this week the concession stand sold a combination of 230 hot dogs and hamburgers and earned $138.50 for the athletic programs if x represents the number of hot dogs sold and y represents the number of hamburgers sold which system of equations represents this situationa 0.75x + 0.50y = 230 x + y =138.50b 0.50x + 0.75y =138.50 x + y =230 c 0.75x + 0.50y =138.50 x + y =230 d 0.50x + 0.75y =230 x + y =138.50

Solve this equation using substitution. {4x + y = −2} {4x + 6y = 44}

The table shows the relationship between the number of cups of cereal and the number of cups of raisins in a cereal bar recipe: number of cups of cereal number of cups of raisins 8 2 12 3 16 4 molly plotted an equivalent ratio as shown on the grid below: a graph is shown. the title of the graph is cereal bars. the horizontal axis label is cereal in cups. the x-axis values are 0, 20, 40, 60, 80,100. the vertical axis label is raisins in cups. the y-axis values are 0, 10, 20, 30, 40, 50. a point is plotted on the ordered pair 40,20. which of these explains why the point molly plotted is incorrect? (a) if the number of cups of cereal is 40, then the number of cups of raisins will be10. (b)if the number of cups of raisins is 40, then the number of cups of cereal will be10. (c) if the number of cups of cereal is 40, then the number of cups of raisins will be 80. (d) if the number of cups of raisins is 40, then the number of cups of cereal will be 80.
