Ahotel charges an 8% tax, as required by law to pay the city. if mr. and mrs. lafferty paid $167.40, what was their bill before the tax was added to it?

Let x is the original bill
x + 0.08x = 167.4
1.8x = 167.4
x = 167.4 / 1.8
x = 155

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

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

0=6x+2y+10 is equivalent to the simplified form: y= -3x - 5• parallel lines always have the same slope, different y intercept knowing this, we can say the slope, or m of the line parallel to y= -3x - 5 is -3.m= -3 hope this could !
