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

Answer:

27 flowers

Step-by-step 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
