Question

A fast food chain sold $4.5$ million hamburgers in the spring, $5$ million in the summer, and $4$ million in the fall; the number sold in the winter is unknown. If exactly $25\%$ of the chain's hamburgers are sold in the fall, how many million hamburgers are sold in the winter?

$2.5$

$3$

$3.5$

$4$

$4.5$

Solution:

If the fall sales of $4$ million are $25\%$ of the yearly total, then the yearly total is $16$ million.

The winter sales are $16 - (4.5 + 5 + 4) = 2.5$ million.

Thus, the correct answer is A .
