Mrs. Finch's first grade class was holding a used book sale. Some books were sold for $0.25 anc others sold for $0.35. The first customer spent $3.15 for 11 books. How many $0.25 books and
$0.35 books did the customer buy?

7, 4

Step-by-step explanation:

x = 25 cent books, y = 35 cent books

x + y = 11

.25x + .35y = 3.15   Multiply this to get the x to be the same, x4=

x + 1.4y = 12.6    Now subtract the first equation

-x  + y   =  11

.4y = 1.6

y = 4

11 - 4 = 7    x = 7
