Let the two numbers be x and y

![\sf{ x + y = 11......eq(1) }](https://tex.z-dn.net/?f=%5Csf%7B%20x%20%2B%20y%20%3D%2011......eq%281%29%20%7D)

![\sf{ x - y = 19 }](https://tex.z-dn.net/?f=%5Csf%7B%20x%20-%20y%20%3D%2019%20%7D)

![\sf{ - 2y = 8}](https://tex.z-dn.net/?f=%5Csf%7B%20-%202y%20%3D%208%7D)
![\sf{ y = 8/(-2) }](https://tex.z-dn.net/?f=%5Csf%7B%20y%20%3D%208%2F%28-2%29%20%7D)
![\sf{ y = - 4 }](https://tex.z-dn.net/?f=%5Csf%7B%20y%20%3D%20-%204%20%7D)
![\sf{\red{Thus ,\: the\: value\: of \: y = -4}}](https://tex.z-dn.net/?f=%5Csf%7B%5Cred%7BThus%20%2C%5C%3A%20the%5C%3A%20value%5C%3A%20of%20%5C%3A%20y%20%3D%20-4%7D%7D)

![\sf{ x = 11 - y }](https://tex.z-dn.net/?f=%5Csf%7B%20x%20%3D%2011%20-%20y%20%20%7D)
![\sf{ x = 11 - (-4 ) }](https://tex.z-dn.net/?f=%5Csf%7B%20x%20%3D%2011%20-%20%28-4%20%29%20%20%7D)

![\sf{ x = 15 }](https://tex.z-dn.net/?f=%5Csf%7B%20x%20%3D%2015%20%7D)
Hence, The value of x and y are 15 and (-4) .
To find this we need to do 60 divided by 4/5 or 60*5/4 which is the equal to <span>75

The customers pay $13.00 for renting a bicycle, plus $1.75 per hour, so
2 hours (on the first table) -> $13.00 + ($1.75x2) = $16.50
If you do this for each value of the table, you will see the correct answer is A.
