Part A: There are 114 red marbles
Part B: There are 114 red marbles because if you multiply the ratio 19:1 times 6 you would get 114:6 (added together gives you 120)
Since 20 percent of 175 is 35, the total cost of the meal is 210. Dividing that between 5 people, each person would pay $42.
1 quart is 2 pints so 1 would be 2 would be 4 3would be 6 etc so for the graphs the coordinates would be (1,2) (2,4) (3,6) etc..
