Question

Фермер запланував посадити розсаду: а рядів помідорів і b рядів перцю по 10 штук у кожному ряді. Складіть вираз для обчислення кількості кущів розсади, що запланував посадити фермер. Обчисліть, якщо а = 24, b = 22. Чи вистачить фермерові 900 грн, щоб придбати таку кількість розсади, якщо один кущ розсади коштує 2 грн? У разі якщо цих грошей не вистачить, змініть значення a або b так, щоб йому вистачило 900 грн

Answer 2

Calculation of the Number of Seedlings

To calculate the number of seedlings the farmer plans to plant, we need to determine the total number of rows of tomatoes and peppers and then multiply it by the number of seedlings in each row.

Given that there are a rows of tomatoes and b rows of peppers, with 10 seedlings in each row, the total number of seedlings can be calculated using the following expression:

Total number of seedlings = (a rows of tomatoes + b rows of peppers) * 10 seedlings per row

Substituting the given values, where a = 24 and b = 22, we can calculate the total number of seedlings as follows:

Total number of seedlings = (24 + 22) * 10 = 46 * 10 = 460 seedlings.

Therefore, the farmer plans to plant 460 seedlings.

Affordability of the Seedlings

To determine if the farmer can afford to purchase the planned quantity of seedlings, we need to calculate the total cost of the seedlings and compare it to the farmer's budget.

Given that each seedling costs 2 gryvnias, the total cost of the seedlings can be calculated using the following expression:

Total cost of seedlings = Total number of seedlings * Cost per seedling

Substituting the given values, where the total number of seedlings is 460 and the cost per seedling is 2 gryvnias, we can calculate the total cost of the seedlings as follows:

Total cost of seedlings = 460 * 2 = 920 gryvnias.

Therefore, the total cost of the seedlings is 920 gryvnias.

Since the farmer has a budget of 900 gryvnias, it is clear that the farmer does not have enough money to purchase the planned quantity of seedlings. The total cost of the seedlings exceeds the farmer's budget.

To make the purchase affordable within the budget of 900 gryvnias, the farmer can either reduce the number of rows of tomatoes (a) or the number of rows of peppers (b). By adjusting these values, the farmer can find a combination that allows them to purchase the desired quantity of seedlings within their budget.
