Explanation:

First Sub - Question (Yellow Roses Problem)

Step 1: Identify the formula

We know that the initial number of yellow roses minus the number of yellow roses bought by Aparna equals the remaining number of yellow roses. Let the number of yellow roses bought by Aparna be \(x\). So the formula is \(45 - x=29\).

Step 2: Solve for \(x\)

To find \(x\), we can rearrange the formula as \(x = 45-29\). Calculating \(45 - 29\), we get \(x = 16\)? Wait, no, wait. Wait, the options are 12, 14, 36, 72. Wait, maybe I misread. Wait, the problem says "Aparna buys some yellow roses. Then the store has 29 yellow roses left." Initial is 45. So \(45 - x=29\), so \(x = 45 - 29=16\). But 16 is not in the options. Wait, maybe the initial number is 43? Wait, the image says "The store has 43 yellow roses. Aparna buys some yellow roses. Then the store has 29 yellow roses left." Oh! I misread 43 instead of 45. So \(x=43 - 29\).

Step 3: Calculate the value

\(43-29 = 14\).

Step 1: Identify the operation

To estimate the total number of shirts, we need to add the number of solid shirts and striped shirts. The number of solid shirts is 21 and striped is 18.

Step 2: Estimate the sum

We can round 21 to 20 and 18 to 20, but a better estimate is to just add them. \(21+18 = 39\), which is close to 40.
