The cooking time for a mini-loaf of bread is 5 minutes longer than half the time it takes to bake a regular-sized loaf of bread. If it takes 25 minutes to bake a mini-loaf, how long does it take to bake a regular-sized loaf?

Let the regular loaf’s baking time be R minutes. The mini-loaf takes half that time plus 5 minutes, so 25 = R/2 + 5. Subtract 5 to get R/2 = 20, then multiply by 2: R = 40 minutes. The correct choice is 40 minutes.
