Question: Thomas is training at the gym to prepare for a competition. He trained for 5 hours every day for a month (30 days). If he continues to train for the next 12 days, how many hours will he spend on training in total?
Answer with step-by-step thinking: In total Thomas would train on 30 + 12 = 42 days. Thomas trained 5 hours every day, which would bring us to 42 * 5 = 210 hours of training in total.
So the answer is 210.


Question: It takes Matt 2 minutes per problem to do his math homework with a calculator and 5 minutes per problem without a calculator. If Matt's assignment has 20 problems, how much time will using a calculator save?
Answer with step-by-step thinking: First find the time difference per problem: 5 minutes / problem - 2 minutes / problem = 3 minutes / problem. Then multiply that number by the number of problems to find the total time difference: 3 minutes / problem * 20 problems = 60 minutes.
So the answer is 60.


Question: Last night, Jim bought a $7 lamp and a bulb which cost $4 less. If he bought 2 lamps and 6 bulbs, how much did Jim pay in all?
Answer with step-by-step thinking:
The cost of the bulb is $7 - $4 = $3. The cost of 2 lamps is $7 x 2 = $14. The cost of 6 bulbs is $3 x 6 = $18. Jim paid a total of $14 + $18 = $32.
So the answer is 32.
