Answer:
110.7989332 percent increase
Explanation:
percent increase = (new - original)/ original
the new amount is in 2018 = 363844490
the original amount is in 1950 = 172602624
substitute in
percent increase = (363844490 - 172602624)/ 172602624
percent increase = (191241866)/172602624
percent increase = 1.107989332
multiply by 100 to make a percent from the decimal form
1.107989332*100
110.7989332 percent increase
