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

• math -

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 \$
