The line $y = 10x - 45$ is already written in the $y = mx+q$ form. This means that $m$ is the slope. If two lines are perpendicular, their slopes are the anti-inverse of each other, i.e. their product is -1.

So, our perpendicular line has a slope of $-\frac{1}{10}$

Finally, we want a line passing through (1,1) with slope $-\frac{1}{10}$ :

$y-1 = -\dfrac{1}{10}(x-1) \iff y = -\dfrac{x}{10} + \dfrac{1}{10}+1 = -\dfrac{x}{10} + \dfrac{11}{10}$

Judy Ring purchased a watch with a retail price of $8,000. She still has to pay a sales tax of 6% and an excise tax of 10%. Sinc

Bumek [7]

The total purchase price of the watch is: $9,300

$8,000 + (0.06 × $8,000) + (0.10 × 8,000) + $20

$8,000 + $480 + $800 + $20
