4.0217391 %

Step-by-step explanation:

The original prices times the tax rate  is equal to the tax

460 * tax rate = 18.50

Divide each side by 460

tax rate = 18.50/460

tax rate =.040217391

writing as a percent ( multiply by 100)

4.0217391 %

Step-by-step explanation:

x * 450 = 18.5                     This means that 450 * a % = 18.50. Divide by 450

x * 450/450 = 18.5/450

x = 0.041111

Multiply by 100 to get a percent.

0. 0411 * 100 = 4.11 %
