The tax rate is 3%

STEP - BY - STEP EXPLANATION

Problem Given:

The tax rate is $22.20 on the purchase of a dinning room set for $740. Find the sale tax rate.

The sale tax rate can be calculated using the formula below:

[tex]\frac{new\text{ value}}{\text{original value}}\times100\text{ \%}[/tex]

Substitute the value and simplify.

[tex]\frac{22.20}{740}\times100\text{ \%}[/tex][tex]=0.03\times100\text{ \%}[/tex][tex]=3\text{ \%}[/tex]

Hence, the tax rate is 3%
