Express the answer in scientific notation to two decimals unless requested otherwise.

A company produced 2,600,000 small appliances in one year and made a profit of $6,690,000. What was the profit on each appliance?

$6,690,000/2600000 = $2.57 per appliance.

I don't see why you would want to express $2.57 in scientific notation.

2.57 x 10^1 looks just plain silly.

actually 2.57 x 10^1

should read
2.57 x 10^0

I guess I was concentrating so much on the silly answer that I messed up my typing.

To find the profit on each appliance, we need to divide the total profit by the total number of appliances produced.

Profit on each appliance = Total profit / Total number of appliances

Total profit = $6,690,000
Total number of appliances = 2,600,000

Profit on each appliance = $6,690,000 / 2,600,000

Calculating this gives us:

Profit on each appliance = $2.5730769

Expressing this in scientific notation to two decimals, we get:

Profit on each appliance = 2.57

To find the profit on each appliance, we need to divide the total profit by the number of appliances produced.

Profit on each appliance = Total profit / Number of appliances

First, let's express the given values in scientific notation to make the calculations easier:

Total appliances produced = 2,600,000 (given)
Total profit = $6,690,000 (given)

2,600,000 can be written in scientific notation as 2.6 x 10^6.
Similarly, $6,690,000 can be written in scientific notation as 6.69 x 10^6.

Now we can substitute these values into the formula:

Profit on each appliance = 6.69 x 10^6 / 2.6 x 10^6

To divide numbers in scientific notation, we divide the coefficients and subtract the exponents:

Profit on each appliance = (6.69 / 2.6) x 10^(6 - 6)
= 2.573 x 10^0

Since any number raised to the power of zero is 1, the profit on each appliance is approximately 2.573.

Therefore, the profit on each appliance is $2.573, or in scientific notation, 2.57 x 10^0.
