Answer:
Given : Brandon buys a radio for $43.99 .sales tax rate is 7%.sales tax is a consumption tax imposed by the government on the sale of goods and services.
Let the price of Radio before the sales tax be $x. Sales tax on $x is 7% x.
Price before sales tax + Amount of sales tax= Cost of Radio.
x+7%x =43.99
Or x+0.07x=43.99
1.07x=43.99
Dividing both sides by 1.07.
x= 41.11
