Answer:
Blank 1: 20 cups of flour
Blank 2: 18.75 cups of flour or 18 3/4 cups of flour.
Step-by-step explanation:
Blank 1: It tells you for every 8 tablespoons of honey they need 10 cups of flour. 16 table spoons of honey is double the 8 tablespoons of honey so you would also double the amount of flour.
2 x 10= 20.
Blank 2: You can find out how much cups of flour is needed for one table spoon of honey by dividing the cups of flour by 8 which gives you 1 and 1/4 or 1.25. Then you can multiply that by 15 for the 15 tablespoons of honey.
1.25 x 15 = 18.75
1 1/4 x 15 = 75/4 or 18 3/4.
3y+6x=90
3y=90-6x
y=30-2x
The x intercept is when y=0, 2x=30, x=15, it represents the maximum possible number of adult tickets sold.
The y intercept is when x=0, y=30, it represents the maximum possible number of student tickets sold.
