Agustin Navarro · Answer 1

155$ is how much they paid before tax

155 * 1.08 = 167.4

1.08 = 108%

or

155 * 0.08 = 12.4

12.4 + 155 = 167.4

0.08 = 8%

your answer is 155

Lincoln Hoover · Answer 2

Let x is the original bill

x + 0.08x = 167.4

1.8x = 167.4

x = 167.4 / 1.8

x = 155

answer: $155 was their bill before the tax was added to it
