Final answer:
The equation that relates the number of ounces of pineapple juice (p) to the number of ounces of frozen lemonade (l) is 2p = l.
Step-by-step explanation:
To write an equation that relates the number of ounces of pineapple juice (p) to the number of ounces of frozen lemonade (l), we can use a proportion. Let's assume that for every ounce of pineapple juice, there are 2 ounces of frozen lemonade. This can be represented as:
p/1 = l/2
To find the equation in terms of p, we can cross multiply:
2p = l
So, the equation that relates p to l is 2p = l.
