baherus [9]

<u>✿</u><u>Answer:</u>

Both sold 18 wristbands and 12 belts

✂----------------------

Let, number of wristbands = x

number of belts = y

$x+y=30$ ➞ $x~5.5$

$5.50x+8.75y=204$ $x1$

$5.50x+5.5y=165\\5.5x+8.75y=204\\---------\\-3.25y=-39$

$y=-39/3.25$

$y=12$

$x=30-12=18$

$So, Both~ sold ~18 ~wristbands ~and ~12~ belts$ .
