Question

Rachel has 3 times as many roses as carnations. She has 12 fewer carnations than daisies. There are 15 daisies. How many flowers does Rachel have in all

Answer 1

27 flowers

Explanation:

Let

x ----> the number of roses

y ----> the number of carnations

z ----> the number of daisies

we know that

`x=3y` ----> equation A

`y=z-12` -----> equation B

`z=15` -----> equation C

substitute the value of z in equation B

`y=15-12=3`

substitute the value of y in equation A

`x=3(3)=9`

so

Rachel have 9 roses, 3 carnations and 15 daisies

In total

9+3+15=27 flowers
