Answer :
To find Juan’s total profit over the 4 days, we can follow these steps:
1. Initial Profit on the First Day:
Juan starts off with a profit of [tex]$12 on the first day. 2. Profit Calculation for Each Subsequent Day: - Day 2: - Amount spent: $[/tex]7
- Amount earned: [tex]$16 - Profit for Day 2: \(16 - 7 = 9\) - Day 3: - Amount spent: $[/tex]12
- Amount earned: [tex]$22 - Profit for Day 3: \(22 - 12 = 10\) - Day 4: - Amount spent: $[/tex]9
- Amount earned: [tex]$18 - Profit for Day 4: \(18 - 9 = 9\) 3. Total Profit Calculation: We sum up the initial profit and the profits from all subsequent days: \[ 12 + (16 - 7) + (22 - 12) + (18 - 9) \] 4. Evaluating the Expression: - Day 2 profit: \(16 - 7 = 9\) - Day 3 profit: \(22 - 12 = 10\) - Day 4 profit: \(18 - 9 = 9\) Adding these values together with the first day's profit, we get: \[ 12 + 9 + 10 + 9 = 40 \] So, the expression needed to find his total profit is: \[ 12 + (16 - 7) + (22 - 12) + (18 - 9) \] And his total profit was: \[ \$[/tex]40
\]
