Answer

Explanation:

Step1: Calculate daily profits

For Day 2: $16 - 7$; For Day 3: $22 - 12$; For Day 4: $18 - 9$.

Step2: Calculate total profit expression

The initial profit is $12$, and the total profit expression is $12+(16 - 7)+(22 - 12)+(18 - 9)$.

Step3: Simplify the expression

First, simplify each part: $16 - 7=9$, $22 - 12 = 10$, $18 - 9=9$. Then $12+9 + 10+9$.

Step4: Calculate the sum

$12+9+10 + 9=40$.

Answer:

Expression: $12+(16 - 7)+(22 - 12)+(18 - 9)$ Total profit: $40$
