Answer:
6%
Explanation:
The tax rate times the purchase amount equals the amount of tax.
We have the purchase amount ($929) and the amount of tax ($55.74). We are looking for the tax rate. Let the tax rate be x.
tax rate * amount = tax amount
x * 929 = 55.74
929x = 55.74
Divide both sides by 929.
x = 55.74/929
x = 0.06
The tax rate is 0.06 as a decimal number. To write it as a percent, move the decimal point two places right.
x = 0.06 = 6%
