How to calculate the difference events given Inthe graph?
For question a.)
The federal cost for social security in scientific notation would be;
525 × 10⁹
= 5.25 ×10²×10⁹
= 5.25 ×10¹¹
For question b.)
The enrollment in Social security in scientific notation would be;
= 48×10⁹
= 4.8× 10¹×10⁹
= 4.8×10¹⁰
For question c.)
The yearly average per person benefit for social security
= 5.25 ×10¹¹+4.8×10¹⁰/2
= 52.5+4.8× 10¹⁰
= 57.3/2
= 28.65 × 10¹⁰
= 2.9× 10¹¹
For question d.)
The average monthly per person benefit would be = $2.42× 10¹⁰.
