51
B.
43
C.
45
D.
47

Answer 1

Answer: C. 45

Explanation:

1. You know that there are 6 tulips for every 9 daisies. Then, if there are 30 tulips, you can write the following expresion, where
`x` is the number of daisies when there are 30 tulips:

`(6)/(9)=(30)/(x)`

2. Then, you must solve for x as following:

`6x=30*9\\6x=270\\x=(270)/(6)\\x=45`

3. Therefore, the answer is 45 daisies.
