Final answer:
The question on Kala's expenditure on chocolates cannot be answered without more information. Instead, an example involving Marie's budgeting for magazines and pies was explained, where the method of multiplying quantity by price to determine total spending was illustrated.
Step-by-step explanation:
The question about how much Kala spent on boxes of chocolates is incomplete, as it does not provide the cost per box or the number of boxes purchased. However, we can discuss a similar problem provided in the reference information, which involves Marie and her weekly budget for magazines and pies.
Calculating Weekly Expenses
To calculate how much Marie spends on magazines and pies each week, we'd start off by noting her total budget, which is $24. If we had the price of each magazine and each pie, as well as the number she plans to buy, we could multiply the quantity by the price to determine the total expenditure for each item. This method of calculation is similar to the examples provided where the total amount spent on fruit is calculated by multiplying the quantity of fruit by its price.
Example Calculation
For instance, if Marie buys 10 magazines at $2 each and 2 pies at $5 each, we would calculate her spending as follows:
10 magazines × $2 each = $20 spent on magazines.
2 pies × $5 each = $10 spent on pies.
In this example, Marie would be exceeding her budget as the total cost ($30) is greater than her weekly budget of $24. Thus, she would need to adjust the quantities purchased to stay within her budget.
This approach to calculating expenses can help Marie manage her budget and make decisions on how much of each item she can afford to buy.
