Answer 2

To solve this problem, we need to find the weight of strawberries in each basket and then calculate the total cost of the purchase.

Let's assume the weight of strawberries in the first basket is x kg. According to the problem, the weight of strawberries in the second basket is 1.6 times less than in the first basket, so it would be 1.6x kg.

We also know that the weight of strawberries in the first basket is 1.44 kg more than in the second basket. So we can set up the following equation:

x = 1.6x - 1.44

To solve this equation, we can subtract 1.6x from both sides:

x - 1.6x = -1.44

Simplifying, we get:

-0.6x = -1.44

Now, we can divide both sides by -0.6 to solve for x:

x = -1.44 / -0.6

Calculating this, we find that x ≈ 2.4 kg.

Therefore, the weight of strawberries in the first basket is approximately 2.4 kg, and in the second basket, it is approximately 1.6 times less, which is 1.5 kg (1.6 * 2.4 = 3.84 kg).

Now, let's calculate the total cost of the purchase. We know that 1 kg of strawberries costs 8.5 UAH, and the empty basket costs 8.4 UAH.

The cost of strawberries in the first basket would be 2.4 kg * 8.5 UAH/kg = 20.4 UAH. The cost of strawberries in the second basket would be 1.5 kg * 8.5 UAH/kg = 12.75 UAH.

Adding the cost of the two baskets (8.4 UAH each), the total cost of the purchase would be:

20.4 UAH + 12.75 UAH + 8.4 UAH + 8.4 UAH = 49.95 UAH.

Therefore, the total cost of the purchase would be approximately 49.95 UAH.
