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=
$ x+ $ y= 304.o5

9.95x+11.5y=305.05
x+y=29
9.95x+9.95y=29*9.95
Or (11.509.95)y=305.05288.55
1.55y=16.5
y=16.5/1.55=10.6, say 11 yellow shirts
2911=18 white shirts
11*11.5+18*9.95=305.6 OK.
