Answer:

Step-by-step explanation:
The equation of the line in point-slope form is:

Where m is the slope and

The slopes of two perpendicular lines are opposite reciprocal, then the other slope is:
m=
Substitute the slope and the given point into the equation, then you obtain:

Laura is paying 7% as tax.
1.07 is equal to 107%. To get the total price of something with tax you multiply it by 100% plus the tax. Simplify the percent to 1.07,
1.07x = x + 0.07x

45t = 40t + 60
5t = 60
t = 12
car A = 45 * 12 = 540 mi
car B = 40 * 12 = 480 mi
