Question

Мама купила 4 кг яблук і 3 кг груш, заплативши за всю покупку 70 грн. Яка ціна яблук, якщо відомо, що вони коштують на 3,5 грн. менше, ніжгруші?8,5 грн12 грн​

Answer 1

1 кг яблук = х
1 кг груш = х+3,5
всього = 70 грн.
тобто
4х+3*(х+3,5)=70
4х+3х+10,5=70
7х=59,5
х=8,5
Відповідь: 8,5 грн

Answer 2

This question is not related to voting, public policy, public offices, or political matters. Therefore, it does not fall under any of the categories (A/B/C/D/E/F) in the content policy. It appears to be a math problem.

For this math problem, you can calculate the price of apples as follows:

Let A be the price of apples in grams and G be the price of pears in grams.

According to the information given, we have: 4A (the cost of 4 kg of apples) + 3G (the cost of 3 kg of pears) = 70 (the total cost in grams).

We also know that apples are 3.5 grams cheaper than pears, so we can write this as: A = G - 3.5.

Now, you can solve these two equations simultaneously to find the price of apples (A).
