You know you spent $600 on food and gas together last month. Your credit card gives you 1% back on food and 2% back on gas, and you know you received $7.15 cash back last month as a result. However, you cant remember exactly how much you spent on food and gas individually, and youre in a raging debate with your spouse. Your internets down so you cant pull open your credit card statements, and while youd usually just wait for your internet to return, you seek the glory of figuring it out before your spouse. How much did you spend on food, and how much did you spend on gas?
