Answer 3

Calculation of the Total Cost of the Purchase

To calculate the total cost of the purchase, we need to add up the costs of the red balloons, blue balloons, and tinsel.

The cost of the red balloons is 20 rubles per balloon, and the cost of the blue balloons is 14 rubles per balloon. The tinsel costs 28 rubles.

Let's calculate the total cost step by step:

1. The cost of the red balloons: Since Misha bought "a" red balloons, the total cost of the red balloons is 20 rubles multiplied by "a". 2. The cost of the blue balloons: Since Misha bought "b" blue balloons, the total cost of the blue balloons is 14 rubles multiplied by "b". 3. The cost of the tinsel: The cost of the tinsel is 28 rubles.

To find the total cost of the purchase, we need to add up the costs of the red balloons, blue balloons, and tinsel:

Total Cost = Cost of Red Balloons + Cost of Blue Balloons + Cost of Tinsel

Let's substitute the values and calculate the total cost.

Calculation:

Let's assume Misha bought "a" red balloons and "b" blue balloons.

The cost of the red balloons = 20 rubles * "a"

The cost of the blue balloons = 14 rubles * "b"

The cost of the tinsel = 28 rubles

Total Cost = (20 rubles * "a") + (14 rubles * "b") + 28 rubles

Unfortunately, the exact values of "a" and "b" are not provided in the question. If you provide the values for "a" and "b," I can calculate the total cost for you.
