Blankets:$32
Towels:$16
You set it up as a system of equations.
I made the blankets x and the towels y.
You get 2 equations:
21x+21y=1008
21x+ 23y= 1040
I solved the system by solving the second equation for 21 x
21x= 1040-23y
And plugged it into the first equation
1040-23y+21y=1008
Y= 16
Then I plugged 16 in for y:
21x+23(16)=1040
X=32
