sara spent $64 on books and towels. she bought three times as many books as towels. how many of each did she buy?
*every item is $8

b = numbers of books
t = numbers od towels
b = 3 t
Total price :
( b + t ) * 8 = 64
( 3 t + t ) * 8 = 64
4 t * 8 = 64
32 t = 64 Divide both sides by 32
t = 64 / 32 = 2
2 towels
b = 3 t
b = 3 * 2 = 6
6 books
2 * 8 $ + 6 * 8 $ =
16 $ + 48 $ = 64 $
