1. A Purple haired Spaniel costs double as much as a
Turquoise haired Spaniel and 150 pounds. If 3 Purple and 6
Turquoise haired spaniels equal 5250 pounds, how much
does a purple haired spaniel and a tortoise haired spaniel
cost individually?
P=2T+150
3P+6T=5250 now substitute 2T+150 for P
3(2T+150)+ 6T=5250 now do the distributive property
6T + 450+6T=5250 now combine like terms
12T+450=3150 take away 450 from both sides
12T= 4800 divide both sides by 12
