To calculate how much Li will have to earn to pay for the skateboarding set, we need to go step by step:
1. Calculate the sale price: 30% off of $54.99 = $54.99 * 0.30 = $16.50 off.
So the sale price is $54.99 - $16.50 = $38.49.
2. Calculate the additional discount after using the coupon: 10% off of $38.49 = $38.49 * 0.10 = $3.85 off.
So the final price before sales tax is $38.49 - $3.85 = $34.64.
3. Calculate the sales tax: $34.64 * 0.0575 = $1.99.
4. Add the sales tax to the final price: $34.64 + $1.99 = $36.63.
Therefore, Li will have to earn $36.63 to pay for the skateboarding set.
