Answer the following question.
A small, old, wooden bridge can hold up to 100 kilograms at once. Mike, Megan, and Kelly are three children who decided to cross the bridge at the same time. Kelly weighs 34 kilograms, which is 15% less than Megan. Mike weighs 5 kilograms more than Megan. How much too much do the three children weigh together to cross the bridge?
Step-by-step reasoning process: If Kelly weighs 15% less than Megan, this means Kelly's weight is 100 - 15 = 85% of Megan's weight. 85% is 0.85, so Megan weighs 34 / 0.85 = 40 kilograms. Mike weighs 5 kilograms more than Megan, so he weighs 40 + 5 = 45 kilograms. In total all three kids weigh 34 + 40 + 45 = 119 kilograms. That means to cross the bridge safely, they weigh 119 - 100 = 19 kilograms too much.
The answer is 19.

Answer the following question.
Two stores sell the same model of smartphone, but they offer it at different prices and with different discounts. Store A lists the smartphone at a full price of $125 and offers an additional discount of 8%. Store B lists the same smartphone for $130 and offers an additional discount of 10%. After both stores' discounts are applied, how much cheaper is store A's smartphone than store B's smartphone?
Step-by-step reasoning process: Store A has a $125 x 8 / 100 = $10 discount. So the smartphone from store A will only cost $125 - $10 = $115. Store B has a $130 x 10 / 100 = $13 discount. So the smartphone from store B will only cost $130 - $13 = $117. Thus, store A's smartphone is $117 - $115 = $2 cheaper than that of store B.
The answer is 2.

Answer the following question.
Danielle bought a new house for $280k. She paid a $40k deposit on the house, and pays the rest using a mortgage that is spread out over 10 years. Danielle makes equal payments every month and at the end of the 10 years, the entire balance will be paid off. How much, in thousands of dollars, does Danielle pay each month?
Step-by-step reasoning process: After paying the deposit, Danielle still has to pay a total of $280k purchase price - $40k deposit = $240k via her mortgage. As the mortgage is over 10 years, Danielle’s payments need to total $240k mortgage balance / 10 years = $24k per year. So each month, Danielle has to pay $24k per year / 12 months in a year = $2k per month.
The answer is 2.
