Question: Elizabeth wants to buy the steak knives from a bridal registry as a wedding gift. The couple registered for 2 steak knife sets and each set contains 4 steak knives. If Elizabeth buys both sets and they cost $80.00 per set, how much does each single steak knife cost?
Answer with step-by-step thinking: Each steak knife set has 4 steak knives and Elizabeth bought 2 sets so there are 4 * 2 = 8 steak knives in total. Each steak knife set costs $80.00 and she bought 2 sets so she spent $80 * 2 = $160.00. Both sets cost $160.00 and there are 8 knives in total so each knife costs 160 / 8 = $20.00 each.
So the answer is 20.


Question: Josh has a device that automatically records the temperature in his lab every 5 seconds. To perform an analysis of environmental conditions, Josh lets the device record data for one hour. How many instances of data will the device record?
Answer with step-by-step thinking: There are 60 minutes in an hour, and 60 seconds in a minute so there are 60 * 60 = 3600 seconds in an hour. The device records data every 5 seconds so there will be 3600 / 5 = 720 instances of data in an hour.
So the answer is 720.


Question: Sarah wants to start a cupcake business and was approved for a business loan. The loan has 0% interest if she pays the entire amount back in 5 years, which she decides to do. If she put $10,000 down as a down payment and her monthly payments are $600.00, how much was her loan for (including the down payment)?
Answer with step-by-step thinking:
To avoid interest she'll make payments for 5 years. There are 12 months in 1 year so that's 5 * 12 = 60 months. Each monthly payment is $600.00 and she'll pay that for 60 months for a total of 600 * 60 = $36,000. She also put $10,000 down as a down payment and her monthly payments came out to $36,000 so her loan was for 10000 + 36000 = $46,000.
So the answer is 46000.
