In sakura's garden for every 5 red flowers, there are 10 yellow flowers. There are a total of 75 yellow and red flowers in her garden. How maNY red flowers are in sakura'sgarden?

Let x = the number of yellow flowers

Let y = the number of red flowers.

There are a total of 75 flowers, therefore

x + y = 75 (1)

For every 5 red flowers, there are 10 yellow flowers, therefore

x = 2y (2)

Substitute (2) into (1).

2y + y = 75

3y = 75

y = 25

x = 2*y = 50

Answer: 25 red flowers.
