Amy biked 12 miles yesterday. If she biked 3 miles less than twice as far as yesterday, how many miles did she bike in total in the two days?
Twice the distance Amy biked yesterday is 12*2 = <T>multiply(12, 2)=24 miles
If Amy biked 3 miles less than twice as far as yesterday, she biked 24-3 = <T>subtract(24, 3)=21 miles today.
The total distance she biked in the two days is 21+12 = <T>add(21, 12)=33 miles
