A store sold 29 sweatshirts. White ones cost $ 9.95 and yellow ones cost $ 11.50
If $ 305.05 worth of sweatshirts were sold, how many of each were sold.
Let x=the number of white sweatshirts
Let y= the number of yellow sweat shirts
Complete the system of equations.
$ x+ $ y= 304.o5
y=16.5/1.55=10.6, say 11 yellow shirts
29-11=18 white shirts
