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 year's annual production was 650,000 boxes.

directions of trains = towards each other

Time to meet = 150/(60+90) = 150 miles / 150 mph = 1 hour

Speed of fly = 120 mph

Since fly has been flying for one hour, it travelled 120 miles.
