Brandon buys a radio for 48.43 dollars in a state where the sales tax is 7% ​
Elza [17]

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

Cost of Radio before tax = $41.11

Sales tax paid = 43.99-41.11= 2.88

Tax paid = $2.90 (To the nearest cent)
