Question

Please help me, I need to get a good score on this test so bad.

Answer 1

1. (100 - 25) / 100...x 100
     75/100 = 0.75....x 100 = 75% decrease

2. (66 - 45) / 66....x 100
     21/66 = 0.318...x 100 = 31.8% increase

3. 36,000(1.05) = $ 37,800

4. 64(1.25) = 80

5. having trouble with this...what is the tax rate ? 75%...or 7.5%
