+73 For each problem below, solve algebraically. Then, use a table or graph to check your answer.
+37146 10 (million) = ,5 * 1.21^(x/2) divide both sides by .5
20 = 1.21^(x/2) Take LOG of both sides
log 20 = x/2 Log 1.21 divide by log 1.21
15.716 = x/2 mult both sides by 2
x =31.43 years
1988 + 31.43 years = 2019
