Question

ann paid $36.00 for three used books. the first cost 1/2 as much as the second and 1/3 as much as the third. find the cost of each?

Answer 1

Let x equal the price of the first book.

Now, using x, formulate the prices of books 2 and 3.

Book 1 + Book 2 + Book 3 = $36

Answer 2

@lynn17 Hints: Let f is the first, and s is the second:
"the first costs 1/2 as much as the second"
-> s = 2f

Answer 3

Similarly, can you find the relation between the first and the third:
" the first cost 1/3 as much as the third"
