Andy buys a computer that costs $575. The sales tax is 5%. Describe a method he could use to estimate the sales tax. Will the estimated tax be greater than or less than the actual tax? Explain.​

Step-by-step explanation:

575 is almost 600

0.05(600) = $30

The tax estimate is over the actual value as we rounded the purchase price upward.

0.0076, if you meant 4.125 divided by 0.03125 it would be 132

step-by-step explanation:

first you have to move the decimal in 0.03125 over until its behind the 5 which is 5 places over. now the number is 3125

then you have to move the decimal in 4.125, 5 places over. now the number is 4,112,500.

now you divide like you would normally would and get 0.0076
