Question

American cheese 0.45 to 4.26 what is the percent increase

Answer 1

For this case we have the following rule of three:
0.45 ------> 100%
4.26 ------> x
Clearing x we have:
x = (4.26 / 0.45) * (100)
x = 946.6666667%
Thus, the percentage of growth is:
946.6666667 - 100 = 846.6666667
Rounding:
846.7%
Answer:
the percent increase is:
846.7%
