could you please awnser this: Rosie spent $2 on stamps. She bout three times more 10 cent stamps than 20 cent ones. How many of each did she buy? thank you.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

 
Let x be the number of 20-cent stamps Rosie bought.
Then the number of 10-cent stamps is 3x.


The "value" equation is 

3x*10 + 20*x = 200,   or

30x + 20x = 200,   or   

50x = 200.

Hence,

x =  = 4.

Rosie bought 4 20-cent stamps and 3*4 = 12 10-cent stamps.
