Question

In a certain clothing store, 3 shirts and 5 ties cost $60, and 2 shirts and 3 ties cost $39. What is the cost of each shirt?

If s = the cost of a shirt and t = the cost of a tie, which system of equations represents the problem?

Answer 1

3 shirts cost 3s dollars. 5 ties cost 5t dollars. They add to 3s+5t, and this result is given to be $60. So

3s + 5t = 60

is your first equation

Answer 2

Use the same idea to find the second equation
