Kellogg's produced 715000 boxes of cornflakes this year. This was 110% of annual production last year. What was last year's annu
Charra [1.4K]
Let last year product be x boxes.

110% of x means \displaystyle{  \frac{110}{100}\cdot x.

Thus, we solve the equation:

                                  \displaystyle{ \frac{110}{100}\cdot x=715,000.

Multiplying both sides by  \displaystyle{ \frac{100}{110}, we have:

                    \displaystyle{ x=715,000 \cdot \frac{100}{110}=650,000.


Answer: Last <span>year's annual production was 650,000 boxes.</span>
