Answer:
$17.60
Explanation:
We know that Emma spent $16.00 on her food. 
There is a 10% tax. 
Therefore, the total bill will be the price without tax plus the tax. 
The price without tax is $16.00. 
Tax is 10%. So, the tax will be 10% of 16. 
10% of 16 is the same as 0.1(16) or 1.6. 
So, the tax is $1.60. 
Therefore, the total bill is: 
$16.00+$1.60=$17.60. 
Emma’s total bill comes to $17.60
