A television cost $375 it is on sale for 25% off and there a 6.5% sales tax

Answers

25% of $375 is:
$375* (25/100)= $93.75.

The cost of the television after sale off and before the sales tax is:
$375- $93.75= $281.25

The sales tax is:
$281.25* (6.5/100)= $18.28

The price of the television including everything is:
$281.25+ $18.28= $299.53

A television costs 375 dollars.It is on sale for 25% and there’s a sales tax of 6.5%Let’s calculate to get the answer.Original Price = 375 dollarsLet’s add the 6.5% sales tax=> 6.5% = 6.5 / 100 = 0.065=> 375 * 0.065 = 24.375=> 375 + 27.375 = 399.375Let’s subtract the 25% discount=> 25% = 25 / 100 = .25=> 399.375 * .25 = 99.84375=> 399.375 - 99.84375 = 299.53.Thus the new price of the television is 299.53 with the sales tax and discount.

How can you use models to explain why 3.1=3.10?

Answers

Answer:

3.1 = 3.10 because adding zero (0) in decimal number at the right most side doesn't affect the number as the same way adding zero at the left most side of a number doesn't affect the number.

Also, 3 and 1 ones are the same as 3 and 10 tenths.

Adding a zero would not do anything after a decimal because 1 is the tenth, and adding a zero will still make it 3 wholes and 1 tenth....0 hundredths.

That is why 3.1 = 3.10
