### Instruction:
 约翰每天吃3顿饭。早餐含有500卡路里。他的午餐比早餐多25%的卡路里。晚餐的卡路里是午餐的两倍。他还有3杯300卡路里的奶昔。他一天摄入多少卡路里？


### Response:
 早餐是<<500=500>>500卡路里
午餐比早餐多25%的卡路里，所以是500*.25 = 125卡路里
这意味着午餐是500+125 = <<500+125=625>>625卡路里
晚餐是午餐的两倍，所以是625*2 = <<625*2=1250>>1250卡路里
奶昔每杯300卡路里，所以是3*300 = <<3*300=900>>900卡路里
所以总共他一天摄入500+625+1250+900 = <<500+625+1250+900=3275>>3275卡路里
