Part 1
The sales tax is $37.45 on the purchase of a dining room set for $749. Find the sales tax rate.
To find the sales tax rate, divide the sales tax amount by the purchase price of the dining room set and multiply by 100 to express it as a percentage.
Sales tax rate = (Sales tax amount / Purchase price) * 100
Sales tax rate = (37.45 / 749) * 100
Sales tax rate = 0.0499 * 100
Sales tax rate = 4.99%
Therefore, the sales tax rate is 4.99%.
