Question: John and Anna bought some eBook readers. John bought 15 eBook readers less than Anna did. Unfortunately, John lost 3 eBook readers. If Anna bought 50 eBook readers, how many eBook readers do they have altogether?
Answer with step-by-step thinking: John bought 50 - 15 = 35 eBook readers. John has 35 - 3 = 32 eBook readers after losing some. Together they have 50 + 32 = 82 eBook readers.
So the answer is 82.


Question: Jake's neighbors hire him to mow their lawn and plant some flowers. Mowing the lawn takes 1 hour and pays $15. If Jake wants to make $20/hour working for the neighbors, and planting the flowers takes 2 hours, how much should Jake charge (in total, not per hour) for planting the flowers?
Answer with step-by-step thinking: First figure out how many hours total Jake works by adding the time spent mowing the lawn to the time spent planting flowers: 1 hour + 2 hours = 3 hours. Then figure out how much money Jake makes if he earns $20 / hour for three hours by multiplying the time spent by the pay rate: $20 / hour * 3 hours = $60. Then subtract the money Jake gets paid for mowing the lawn from the total to find how much he should charge in total for planting the flowers: $60 - $15 = $45.
So the answer is 45.
