Question 1145593
<br>
Let
t = # of t-shirts, cost $12 each
p = # of polo shirts, cost $24 each
r = # of rugby shirts, cost $36 each<br>
You manage a clothing store and budget $6000 to restock 200 shirts.
(1) t+p+r = 200
(2) 12t+24p+36r = 6000<br>
If you want to have twice as many rugby shirts as polo shirts...
(3) r = 2p<br>
Substitute (3) into (1) and (2) to get two equations in t and p.<br>
Then solve that pair of equations by your favorite method.
