-29.41%
Step-by-step explanation:
Original number of Pokemon cards with Joe = 85
Updated number of Pokemon cards after sale = 60
Percentage change =![\[\frac{Updated-Original}{Original}*100\]](/tpl/images/0418/2275/e7e7c.png)
=![\[\frac{60-85}{85}*100\] ](/tpl/images/0418/2275/578cf.png)
=![\[-0.2941*100\] ](/tpl/images/0418/2275/5ab05.png)
=-29.41%
Hence the percentage change in Pokemon cards for Joe is -29.41%
The negative sign is due to the fact that the number of cards has decreaased from the original.
