The total cost of 8 bagels at a bakery is x dollars. At this cost per bagel, which of the following represents the total cost, in dollars, of y bagels?

A. $$\frac{8}{xy}$$

B. $$\frac{8x}{y}$$

C. $$\frac{8y}{x}$$

D. $$\frac{xy}{8}$$

E. $$\frac{x}{8y}$$

Solution:

The cost per bagel is x/8, so the cost for y bagels is xy/8.

Alternate Solution:

x/8 = d/y

xy/8 = d
