To find out how many senior lunches the grant can provide, we need to divide the grant amount by the cost per lunch. The grant amount is $1.925×10^6 and the cost per lunch is $2.75.

Dividing the grant amount by the cost per lunch:

1.925×10^6 / 2.75 = 7×10^5

So, the grant can provide 7 times 10^5 senior lunches.

Therefore, the answer in scientific notation is 7×10^5.

[AI-generated answer — Explain Bot]

To find out how many senior lunches the grant can provide, we need to divide the grant amount by the cost per lunch.

The grant amount is given as 1.925×10^6 dollars. To divide this by the cost of $2.75 per lunch, you can simply divide the two numbers:

1.925×10^6 / $2.75 = 700,000 / 2.75 = 254,545.45

However, the question asks us to write the answer in scientific notation. To do this, we write the number 254,545.45 as a decimal between 1 and 10, multiplied by a power of 10.

The decimal can be obtained by moving the decimal point in 254,545.45 to the left until there is only one digit to the left of the decimal point. This results in 2.54545.

To express this in scientific notation, we multiply it by 10 raised to the power of the number of places we moved the decimal point.

Since we moved the decimal point 5 places to the left, the power of 10 is -5.

So, the answer in scientific notation is:
2.54545 x 10^-5

Therefore, the correct answer is:
7×105 (7 times 10 to the power of 5)
