A chef buys 9 cucumbers 18 peppers and 21 tomatoes at the farmers market how much does she spend

Whatever these vegetables cost.

To find out how much the chef spends on cucumbers, peppers, and tomatoes, we need to know the price of each item. Since we don't have that information, I can't provide a specific answer. However, I can help you understand how to calculate the total amount spent if you know the price of each item.

If you know the price per cucumber, pepper, and tomato, you can multiply the quantity of each item by its respective price and then add up the costs.

For example, let's say the price of a cucumber is $1, a pepper is $2, and a tomato is $0.75. To calculate the total cost, you would do the following:

Total cost = (Number of cucumbers × Price per cucumber) + (Number of peppers × Price per pepper) + (Number of tomatoes × Price per tomato)

In this case, it would be:

Total cost = (9 × $1) + (18 × $2) + (21 × $0.75)

You can substitute the actual prices and quantities to find the answer to your specific question.
