Question 1096648
Bily's restaurant ordered 200 flowers for mother's day. 
<pre>
C + R + D = 200
</pre>
They ordered carnations at $1.50 each, roses at $5.75 each and daisies at $2.60 each. ... The total order came to $589.50.
<pre>
1.50C + 5.75R + 2.60D = 589.50 
</pre>
...20 fewer roses than daisies. 
<pre>
R = D - 20

Simplify and solve the system

{{{system(C + R + D = 200, 1.50C + 5.75R + 2.60D = 589.50, R = D - 20)}}}

Answer: 80 carnations, 50 roses, 70 daisies.
