Solution

Solution Steps

Solution Approach

To solve this problem, we can use the concept of proportions. We know that 25 apples cost $20, so we can set up a proportion to find out how many apples can be bought with $100. The proportion is set up as follows: (25 apples / $20) = (x apples / $100). We can solve for x by cross-multiplying and dividing.

Step 1: Set Up the Proportion

We know that $ 25 $ apples cost $ 20 $ dollars. We want to find out how many apples $ x $ can be bought with $ 100 $ dollars. We can set up the proportion as follows:

\[ \frac{25 \text{ apples}}{20 \text{ dollars}} = \frac{x \text{ apples}}{100 \text{ dollars}} \]

Step 2: Cross-Multiply

To solve for $ x $, we cross-multiply:

\[ 25 \text{ apples} \times 100 \text{ dollars} = 20 \text{ dollars} \times x \text{ apples} \]

This simplifies to:

\[ 2500 = 20x \]

Step 3: Solve for $ x $

Now, we can solve for $ x $ by dividing both sides by $ 20 $:

\[ x = \frac{2500}{20} = 125 \]
