To find out how many senior lunches the grant can provide, we need to divide the amount of the grant by the cost per lunch.
The grant amount is $1.925×10^6 (1.925 million dollars) and the cost per lunch is $2.75.
Dividing the grant amount by the cost per lunch:
(1.925×10^6) / (2.75)
This gives us the answer in standard notation as:
1,925,000 / 2.75 = 700,000
To convert this answer to scientific notation, we move the decimal point to the left so that there is only one non-zero digit to the left of the decimal point. In this case, we move the decimal point 5 places to the left.
The answer in scientific notation is therefore:
7 × 10^5
So, the grant can provide 7 × 10^5 (700,000) senior lunches.
To find out how many senior lunches the grant can provide, we need to divide the grant amount ($1.925×10^6) by the cost per lunch ($2.75).
Dividing $1.925×10^6 by $2.75, we get:
1.925×10^6 ÷ $2.75 = 7×10^5
So, the grant can provide 7×10^5 (7 times 10 to the power of 5) senior lunches.
