The Morris family spent 9 days at Lake Tahoe and San Francisco. They spent $350 per day at Lake Tahoe and $475 per day in San Francisco. The total cost of their trip was $3,650.  How manys did the Morris family spend at each location?

T = Tahoe days          cost   350 T

9-T = S                      cost   475 (9-T)      summed  = 3650

 

350 T        +      475 (9-T)        = 3650             solve for T (Tahoe days)     then # San Fran days  =   9 -T
