Answer:
Step-by-step explanation:
Discounting a $\$100$ item by $50\%$ reduces the price to $50\%(\$100)= \$50$. Discounting the $\$50$ price by $30\%$ reduces it to $70\%(\$50)=\boxed{35}$ dollars.
The answer is $35
Initial amount $100
50% discount (100x50%) $50
30% reduction is $50 (50x30%) $15
Price of Snow board after Monday (100-50-15) $35
