The regular price of a bicycle is $\$ 214.00$ and the tax rate is $15 \%$. It is on sale for $10 \%$ off. What is price change? What is the sale price

Step 1 ：First, calculate the tax on the regular price. The tax can be calculated by multiplying the regular price by the tax rate: \(214.0 \times 0.15 = 32.1\)

Step 2 ：Next, calculate the discount on the regular price. The discount can be calculated by multiplying the regular price by the discount rate: \(214.0 \times 0.1 = 21.4\)

Step 3 ：Then, calculate the price change by subtracting the discount from the tax: \(32.1 - 21.4 = 10.7\)

Step 4 ：Finally, calculate the sale price by subtracting the discount from the regular price and then adding the tax: \((214.0 - 21.4) + 32.1 = 224.7\)

Step 5 ：The price change is \(\boxed{10.7}\) and the sale price is \(\boxed{224.7}\)
