Question: A baker is comparing the day's sales to his daily average. He usually sells 20 pastries and 10 loaves of bread. Today, he sells 14 pastries and 25 loaves of bread. If pastries are sold for $2 and loaves of bread are sold for $4, what is the difference, in dollars, between the baker's daily average and total for today?
Answer with step-by-step thinking: The daily average sales of pastries amounts to 20 pastries * $2 / pastry = $40. The daily average sales of bread amounts to 10 loaves of bread * $4 / loaf = $40. Therefore, the daily average is $40 + $40 = $80. Today's sales of pastries amounts to 14 pastries * $2 / pastry = $28. Today's sales of loaves of bread amounts to 25 loaves of bread * $4 / loaf = $100. Therefore, today's sales amount to $28 + $100 = $128. This means the total difference between today's sales and the daily average is $128 $80 = $48.
So the answer is 48.

Question: Dorchester works at a puppy wash. He is paid $40 per day + $2.25 for each puppy he washes. On Wednesday, Dorchester earned $76. How many puppies did he wash that day?
Answer with step-by-step thinking: First find out how much he earned just from puppy washing: $76 - $40 = $36 for puppy washing. Now divide this amount by the payment per puppy: $36 / $2.25 per puppy = 16 puppies.
So the answer is 16.

Question: Martha collected 90 cans while Diego collected 10 more than half the cans collected by Martha. If both of them should collect a total of 150 cans for their project, how many more cans do they need to collect?
Answer with step-by-step thinking:
Half the cans collected by Martha is 90 / 2 = 45. So, Diego collected 45 + 10 = 55 cans. Martha and Diego collected 90 + 55 = 145 cans together. Thus, they need to collect 150 - 145 = 5 more cans.
So the answer is 5.
