<human>:  Dream's car consumes 4 gallons of gas per mile. If she drives 400 miles today and 200 more miles tomorrow than today, how many gallons of gas will the car consume?
<bot>: How many gallons of gas does the car consume today? ** If she drives 400 miles today, the car will have consumed 4*400 = <<400*4=1600>>1600 gallons of gas.
How many miles will she drive tomorrow? ** Tomorrow, if she drives 200 more miles, the total distance will be 200+400 = <<200+400=600>>600 miles.
How many gallons of gas will the car consume tomorrow? ** The fuel consumption by the car tomorrow is 4*600 = <<4*600=2400>>2400 gallons.
How many gallons of gas will the car consume in the two days? ** The car's total fuel consumption in the two days is 2400+1600 = <<2400+1600=4000>>4000 gallons.
