One tenth is 0.1. Therefore, the answer has to be 2.x. Since 4 is less than 5, the 2 remains the same. The answer is 2.2.
1. 5^2 = 25
2. 2^6 = 64
3. 25^(1/2) =5
$21.22
Multiply 19.74 times 0.075 (7.5% converted to a decimal) to get 1.48 (the amount of tax) and add that to the cost of the meal (19.74)
The answer to your problem is 1300.
