Answer: 44.69 dollars
===================================================
Explanation:
The skateboard is on sale for 10%, which means that you save that percentage but have to still pay the remaining 90% of the original cost (note the percentages add to 100%)
This means we'll be involving the multiplier 0.90
We'll also be involving the multiplier 1.0825 which represents an increase of 8.25% (because 100% + 8.25% = 1 + 0.0825 = 1.0825)
Chaining the multipliers together is as straightforward as multiplying those values: 0.90*1.0825 = 0.97425
The order doesn't matter because we can multiply in any order.
The final multiplier is 0.97425 which tells us the final cost is
45.87*0.97425 = 44.6888475 = 44.69 dollars
