Answer:
a. x + 4y = 160
b. 160
c. 40
Step-by-step explanation:
a. We can define the variables as ...
x = number of 1/2-liter bottles
y = number of 2-liter bottles
For the total number of liters to be 80, we require
1/2x + 2y = 80
We can multiply this by 2 to eliminate the fraction.
x + 4y = 160
__
b. The x-intercept is 160. It is the number of 1/2-liter bottles required when no 2-liter bottles are used.
__
c. The y-intercept is 40. It is the number of 2-liter bottles required when no 1/2-liter bottles are used.
Step-by-step explanation:
The first 9 (leftmost) has a value 100 times the value of the second 9 (rightmost).
The first 9 is in the 10,000s place and represents 90,000.
The second 9 is in the hundreds place and represents 900.
90,000 is one hundred times 900.
