Question

Kellogg's produced 715000 boxes of cornflakes this year. This was 110% of annual production last year. What was last year's annual production?

Answer 1

Let last year product be x boxes.

110% of x means
`\displaystyle{ (110)/(100)\cdot x`.

Thus, we solve the equation:


`\displaystyle{ (110)/(100)\cdot x=715,000`.

Multiplying both sides by
`\displaystyle{ (100)/(110)`, we have:


`\displaystyle{ x=715,000 \cdot (100)/(110)=650,000`.


Answer: Last year's annual production was 650,000 boxes.
