Solution

The correct option is A 60
1 balloon = 5 star cards
12 balloons = 12 times 5 star cards.
To find the answer, we can split 12 into tens and ones.

$12 = 10 + 2$

Now, let's multiply these two numbers with 5.

$10 \times 5 = 50$
$2 \times 5 = 10$

To find the final answer, we will have to add these two numbers.

$50 + 10 = 60$

Therefore, Cosmo won 60 star cards.
