Y = mx + b, where m = slope = rise/run and b, the y intercept value
m = 1/1 = 1, then y = x + b.
We notice that y intercept is = - 1
And the equation is:
y = x - 1
20% off means you are paying 80% of the original price ( 100% - 20% = 80%)
Multiply the price of the tv by 80% to find the sale price:
500 x 0.80 = 400
Now multiply the sales price by 1 plus the tax rate to find final cost:
400 x 1.06 = 424
Final price including tax is $424
To convert km/s to m/min, multiply by 1000*60=60000
hence 0.85km/s=51000 m/min
100-15= 85%
2013-2003= 10 years
$71,000 * (0.85^10yrs)= $13,978<span>.</span>08
