A city lunch program for seniors received a grant of 1.925 x 10^6 dollars. Divide that figure by the cost of $2.75 per lunch to find out how many senior lunches that grant can provide. Write the answer in scientific Notation.

a 7 x 10^5
b 0.7 x 10^5
c 7 x 10^6
d 0.7 x 10^6

1 answer

The number of lunches that the grant can provide can be found by dividing the grant amount by the cost per lunch:

(1.925 x 10^6 dollars) / ($2.75 per lunch)

Using the rules of scientific notation for division, we can first divide the numbers and then subtract the exponents:

1.925 / 2.75 = 0.7

10^6 / 10^0 = 10^(6-0) = 10^6

Therefore, the answer in scientific notation is:

0.7 x 10^6

So the correct answer is c) 0.7 x 10^6.
