Q. Last night, the minimum temperature was −23∘C -23^{\circ} \mathrm{C} . That was 5∘C 5^{\circ} \mathrm{C} warmer than the lowest temperature where Ailen can safely use her sleeping bag.\newlineThe following equation describes this situation.\newline−28+5=−23 -28+5=-23 \newlineWhat does −28-28 tell us?\newlineChoose 11 answer:\newline(A) The temperature dropped 28∘C 28^{\circ} \mathrm{C} overnight.\newline(B) The temperature was 28∘C 28^{\circ} \mathrm{C} too cold for using the sleeping bag.\newline(C) Ailen can safely use her sleeping bag down to −28∘C -28^{\circ} \mathrm{C} .
  1. Given Equation Analysis: The given equation is −28+5=−23-28 + 5 = -23. This equation is meant to describe the relationship between the minimum temperature last night and the lowest temperature at which Ailen can safely use her sleeping bag.
  2. Verification of Equation: Let's verify the equation by performing the addition to ensure there are no math errors. −28+5-28 + 5 should equal −23-23.\newline−28+5=−23-28 + 5 = -23
  3. Interpretation of −28∘C-28^\circ\text{C}: The equation is correct, so we can interpret −28-28 in the context of the problem. Since the minimum temperature was −23∘C-23^\circ\text{C} and it was 5∘C5^\circ\text{C} warmer than the lowest temperature Ailen can use her sleeping bag, −28∘C-28^\circ\text{C} represents the lowest temperature at which Ailen can safely use her sleeping bag.
  4. Final Answer: Therefore, the correct answer is (C) Ailen can safely use her sleeping bag down to -28\degreeC.

Question
Luke and Owen have $100 \$ 100 each. Their friend offered to invest their money, promising to return a sum r r times as great as what they invested. Luke was suspicious, so he invested $10 \$ 10 only, but Owen invested his entire $100 \$ 100 . Fortunately, the friend did indeed return a sum r r times as great to each.\newlineThey decided to make another investment. This time, Owen invested all of the money returned to him, and Luke invested the money returned to him and the remaining $90 \$ 90 . Again, they got a sum r r times as great as what they invested. In the end, Owen had $337.50 \$ 337.50 more than Luke.\newlineWrite an equation in terms of r r that models the situation.
