Math 110 Chapter 2.2: Inverse Proportions Name:__________________ 1. If a group of 20 households must support one disabled-person household at a cost of \$40,000/year, how much does each of the 20 households have to pay per year? 2. If that group of 20 households shrinks to 10 households (still aiming to support one disabled-person household at \$40k/year), now how much does each have to pay? 3. If that group of 20 shrinks to 15 instead of 20 or 10, now how much each? ------------------------------------------------- Problems 4-8 are not related to problems 1-3. ------------------------------------------------- 4. If a group of 10 households each pays 6% of their income to support a retired household, and then the group shrinks to 5 households instead, now how much (as a percent) do they each need to pay? 5. If that group of 10 households shrinks to 2 instead, now how much (as a percent) do they need to pay each? 6. If that group of 10 shrinks to 4 instead, now how much each?
