Question

a school band ordered hats for $3 and large t-shirts for 5$ they bought 150 items in all tor $590. graph a system of equations to find how many hats and t-shirts the band ordered

Answer 1

h=hats
s=shirts
Here, you need to do 2 equations.
h+s=150
3h+5s=590
3h+5(150-h)=590
3h+750-5h=590
-2h=-160
h=80
150-80=70 so s=70

i am sorry, this is all i know, but you need to make an equation to graph it.
