Mike counted 5 coins by tens. Then he counted 6 coins by two. Write the total value of the coins.

how can you count 5 of anything by tens?

Lacking data. Don't know value of individual coins.

That’s what the question says

In what language?

Perhaps five tens and six twos (a two cent coin?)
anyway
5*10 + 6*2 = 50 + 12 = 62

To find the total value of the coins, we need to know the value of each coin. Since the problem does not specify the values, let's assume that all the coins have the same value.

First, let's calculate the total value of the 5 coins that Mike counted by tens. Since he counted 5 coins, and each coin is worth the same value, we can multiply the number of coins by the value of each coin. Let's say each coin is worth "x". So, the value of the 5 coins is 5 * x.

Next, let's calculate the total value of the 6 coins that Mike counted by two. Similarly, we multiply the number of coins by the value of each coin. This time each coin is worth "y", so the value of the 6 coins is 6 * y.

To find the total value of all the coins, we need to add the values of the coins counted in each set. So, the total value is 5 * x + 6 * y.
