"Where are we going now?" Xue Yue asked.
"Are you hungry?"
"Uh... a bit hungry." Xue Yue nodded, "I still have half a bag of red bean bread left at home, can we go back to get it? That... that bread is pretty tasty."
"The fuel cost for this car's round trip is enough to buy ten bags of red bean bread, isn't it?" Sun Hang was a bit speechless, "How much is your red bean bread per bag?"
"I bought the bread from the supermarket's close-to-expiration sale... just one and a half yuan per bag." Xue Yue said, "Even after a few days past expiration, it's still edible..."
"At the price of one and a half yuan per bag, the current fuel cost for the round trip can be converted into cash to buy 14.63 bags of nearly expired red bean bread." The main brain, itching for something to do, immediately helped Sun Hang calculate the value of the red bean bread versus the fuel.
