<h3>
Answer: 18 miles</h3>
Reason:
The path is 2 miles and Randy walked it 13 times. He walked a total of 2*13 = 26 miles.
Carla walked the path 22 times, so she walked a total of 2*22 = 44 miles.
The difference of those results is 44-26 = 18 miles.
If you wanted to do the full calculation in one line, then it would be
2*22 - 2*13 = 18
or you could say
2*(22-13) = 18
30% off $ 45
<span>30% of $ 45 = (.3) (45) = $ 13.50 </span>
<span>30% off $ 45 = $ 45.00 - $ 13.50 = $ 31.50
hope this helped:)
