Bill and Steve decide to spend the afternoon at an amusement park enjoying their favorite activities, the water slide and the gigantic Ferris wheel.  Their tickets are stamped each time they slide or ride.  At the end of the afternoon they have the following tickets: 	

 Fun Time Amusements:
Bill's Ticket

Ferris Wheel-{{{f}}}:   stamped one time

Total:  ${{{17.70}}}

	
 Steve's Ticket

Water Slide-{{{w}}}: stamped six times

Ferris Wheel-{{{f}}}:  stamped two times

Total:  ${{{31.1}}} 


How much does it cost to ride the Ferris Wheel?
How much does it cost to slide on the Water Slide?

{{{3w + f = 17.70}}}
{{{6w + 2f = 31.1}}}
_________________________
 
{{{3w + f = 17.70}}}....multiply by {{{2}}}
{{{6w + 2f = 31.1}}}
_________________________________

{{{6w + 2f = 2*17.70}}}
{{{6w + 2f = 31.1}}}
__________________________________subtract


{{{6w + 2f -6w-2f= 35.4-31.1}}}

{{{6w  -6w+ 2f-2f= 35.4-31.1}}}
