Answer: <em>$20.56</em>
Step-by-step explanation:
<em>Let's take our given total and use this equation</em>
<em>25.70(n)</em>
<em>n will equal 0.80 in this case, as they left a 20% tip so we need to find out what 80% of 25.70 is first</em>

<em>$20.56 is the total without the tip!</em>
Rick is 27 years old. Pretend D is David and R is Rick
D+R=81
D=2R
2R+R=81 ---> 3R=81 ---> 81/3=R R=27 3(27)=81 TRY IT!
Essentially, the rule goes as so: odd + odd = even, even + even = even.
Although that may not be the answer you're looking for, it is a math rule that is never debunked and essentially the premises for why you get an even sum practically always depending on the numbers.
Hope this helps!
