Differential Equations

Have you ever observed the movement of the satellites and rockets or how the planets go around the sun in their orbits? How will you determine their motion? Definitely they follow some scientific laws and these kinds of problems are framed as differential equations.

A.F.D.C. was intended to provide mothers with enough to get by — barely — while raising their children. In 1970 three-person families on A.F.D.C. received, on average, $194 a month. Adjusting for inflation, that’s the equivalent of around $15,000 a year today, compared with the $6,000 a family with two children over age 6 ($7,200 if they’re under 6) will receive under the new plan. In 1970, an A.F.D.C. family of three received about 25 percent of median income for three-person families — hardly a generous allowance, but maybe, just, enough to live on. The new American Rescue Plan will give a single parent of two children less than 7 percent of median income c. What is median family income today (2021)? How much will the new relief bill give to a single parent with two children annually?
