Final answer:
Layla makes $45 in profit.
Step-by-step explanation:
Layla makes three dollars in profits for every four dollars of Joe's mix. If Joe makes $60 in profit, we can calculate how much profit Layla makes by setting up a proportion.
Since Layla makes 3 dollars for every 4 dollars of Joe's mix, we can set it up as:
3/4 = x/60
Cross-multiplying, we get: 4x = 3 * 60
Simplifying, we have: 4x = 180
Dividing both sides by 4, we find: x = 45
Therefore, Layla makes $45 in profit.
