Answer 2

Calculation of the Purchase Cost

To calculate the cost of the purchase, we need to find the total cost of the apples and the pineapple.

Given: - Apples: A kg at a price of 150 rubles per kg - Pineapple: 1 at a price of 180 rubles

Let's calculate the cost of the purchase when A = 2.

Cost of Apples: The cost of apples can be calculated by multiplying the weight (A kg) by the price per kg (150 rubles/kg). Cost of Apples = A * 150 rubles/kg

Substituting A = 2: Cost of Apples = 2 * 150 rubles/kg = 300 rubles

Cost of Pineapple: The cost of the pineapple is given as 180 rubles.

Total Cost of Purchase: To find the total cost of the purchase, we add the cost of apples and the cost of the pineapple. Total Cost of Purchase = Cost of Apples + Cost of Pineapple

Substituting the values: Total Cost of Purchase = 300 rubles + 180 rubles = 480 rubles

Therefore, the cost of the purchase, when A = 2, is 480 rubles.

Writing the Expression

The given problem can be represented by the following algebraic expression:

Expression: Cost of Purchase = (A * 150) + 180

Where: - A represents the weight of apples in kg.

Please note that the expression assumes that the weight of the apples is given in kg and the price per kg is 150 rubles. The cost of the pineapple is given separately as 180 rubles.
