A pack of gum costs 75 cents. That is 3 cents less than three times what the pack cost 20 years ago. Which equation could be used to find the cost of the gum 20 years ago?

A0.3x - 0.3 = 0.75
0.3x - 0.3 = 0.75
B0.03x - 0.3 = 0.75
0.03x - 0.3 = 0.75
C3x - 0.03 = 0.75
3x - 0.03 = 0.75
D3 - 3x = 75
3 - 3x = 75
E3x + 3 = 75
