Rob brought a hat and 3 shirts for 35$. Dan brought 2 hats and a shirt for 20$. Which system of equations can be used to find s , the cost of one shirt and h , the cost of one hat

Step-by-step explanation:

Given data

let hats be h

and shirts be s

Rob brought a hat and 3 shirts for 35$. Dan brought 2 hats

h+3s= 35--------1

and a shirt for 20$

2h+s= 20--------2

Hence the systems of equations is given as

h+3s= 35--------1

2h+s= 20--------2
