Given that in the jar, navy beans and white beans in a ratio of 1:9. Let the amount of navy beans be [tex] x [/tex].
Then, the amount of white beans in the jar is [tex] 9x [/tex].
Given that amount of navy beans is [tex] x=90 [/tex].
Total amount of beans in the jar is [tex] x+9x=10x =10*90=900 [/tex].
