To find out how much the skateboarding set will cost after the discount, we need to first calculate the sale price.
The set is on sale for 30% off, so we can find the sale price by subtracting 30% of the original price from the original price:
Sale price = $54.99 - 30% of $54.99
= $54.99 - (30/100) * $54.99
= $54.99 - (0.3) * $54.99
= $54.99 - $16.50
= $38.49
Next, we need to find the total price after applying the additional 10% discount. We can do this by subtracting 10% of the sale price from the sale price:
Total price = Sale price - 10% of Sale price
= $38.49 - (10/100) * $38.49
= $38.49 - (0.1) * $38.49
= $38.49 - $3.85
= $34.64
Now, we need to calculate the amount of sales tax on the total price. We can do this by multiplying the total price by the sales tax rate:
Sales tax = 5.75% of total price
= (5.75/100) * $34.64
= $1.99
Finally, to find out how much Li will have to earn to pay for the skateboarding set, we need to add the total price and the sales tax together:
Total cost = Total price + Sales tax
= $34.64 + $1.99
= $36.63
Therefore, Li will have to earn $36.63 to pay for the skateboarding set.
Li wants to buy a skateboarding helmet and pads. She sees a set she likes at a sporting goods store. The set costs $54.99. It is on sale for 30% off. Li has a coupon that will take an additional 10% off the sale price. She lives in a state that charges 5.75% sales tax. How much will Li have to earn to pay for the skateboarding set?
