Victor has a bag of dimes and quarters. He has a total of 36 coins worth $5.40. Let x represent the number of dimes and y represent the number of quarters.

Which system of equations would be used to find out how many dimes and quarters Victor has?

{x+y= 5.4
0.1x +0.25y =36

{x=36−y
x+y=5.4

{y=x+36
x+y=5.4

{x+y=36
0.1x+0.25y=5.4
