Question

A calculator costs $12.00. If the sales tax is 7%, what is the total price?

Answer 1

Cost and tax value of an object

Its calculated by

Total price = Cost + sales tax

Total price = 12 + 7% of 12

Now find 7% of 12

Then 12.00 represents 100%

So. 1.2 represnts 10%

And 1.2/2 = 0.6. Reprs. 5%

And. 1.2/5 = 0.24. Reprs. 2%

Now add 5% + 2% = 7% = 0.6 + 0.24 = 0.84

Then 7% is $0.84

Now finally add $12.00 + $0.84 = $12.84

Total price= $12.84
