At the local pet store, zebra fish cost $2.05 each and neon tetras cost $2.30 each. If Sameer bought 13 fish for a total cost of $28.40, not including tax, how many of each type of fish did
he buy?

0.16 or 16%

step-by-step explanation:

lets take a coin for example.

if you toss it twice, it has a 1/4 chance of landing on heads both times because 1/2 * 1/2 is 1/4.

with the cards, the chance of picking dog is 0.4. having two people pick one is like picking a card twice in a row. so 0.4 * 0.4 is 0.16, or 16%

the square root of what number? if you add that, then someone will probably answer the question.
