Kurt have 93 United States stamps in his collection.
Step-by-step explanation:
Given,
Number of stamps = 155
Let,
Stamps of United State = x
Stamps of Canada = y
According to given statement;
x+y=155 Eqn 1
x = 1.5y Eqn 2
Putting value of x from Eqn 2 in Eqn 1
[tex]1.5y+y=155\\2.5y=155[/tex]
Dividing both sides by 2.5
[tex]\frac{2.5y}{2.5}=\frac{155}{2.5}\\y=62[/tex]
Putting y=62 in Eqn 2
[tex]x=1.5(62)\\x=93[/tex]
Kurt have 93 United States stamps in his collection.
