Question

If the ratio of red flowers to yellow flowers in the local park is 9:5 and there are approximately 1,000 red or yellow flowers currently blooming in the park, about how many of them are yellow? You may need to round to the nearest whole number.

Answer 1

Answer:

There are about 357 yellow flowers in the park

Step-by-step explanation:

Let

x -----> number of red flowers

y ----> number of yellow flowers

we know that

$\frac{x}{y}=\frac{9}{5}$

$x=\frac{9}{5}y$ -----> equation A

$x+y=1,000$ -----> equation B

substitute equation A in equation B and solve for y

$\frac{9}{5}y+y=1,000$

$\frac{14}{5}y=1,000$

$y=1,000(5)/14\\y=357$

therefore

There are about 357 yellow flowers in the park
