Question

A Family refers to a group of two or more people related by birth, marriage, or adoption who reside together. In 2000, in country A, the average family net worth was $210,000, and there were about 7.5 x 10 to the 7th power) families. Calculate the total family net worth in Country A in 2000

Answer 1

The big numbers make this problem look tougher than it really is. Figure this out, if one apple costs 10cents, then how much do 5 apples cost? Similarly, if one family is worth $210000, and there are 7.5 *10^7 families then what is the total wealth?

Answer 2

For this one......7.5 * 10 to the 7 power?

Answer 3

What is the slope of the line M=

Answer 4

For the family worth problem, the answer would be (worth of one family) x {number of families) = $210000 x 7.5 *10^7 = $ 1.575*10^13.
For the slope of the line compare its equation to the general equation of a line, the line you have drawn is y = 2.
Compare is with y = m*x + c; where ' m ' is the slope and ' c ' is some constant number.
