At a used book sale, Sarah bought x paperback books priced at $0.25 each and y hardcover books priced
at $0.45 each. She bought a total of 8 books and paid $2.60 in all. Solving which of the following equations
would give the correct values of x and y?
Ox+y=8
0.25x+0.45y = 2.6
Ox+y=8
0.45x+0.25y = 2.6
Ox+y=2.6
0.25x+0.45y = 8
○ xy = 8
2.6xy = 1
