Divide the sale price by the original price:
56 / 89 = 0.7
Multiply by 100:
0.7 x 100 = 70%
The sale price is 70% of the original price, so the discount would be 30% (100-70= 30)
The answer is 45.65
45 + 6.5 = 45.065
45 divided by 6.5 over a hundred = 45 + 0.065
Thats how you get 45.65

Substitute the values of x to the equation of the function f:

Therefore we have two points (-1, 7) and (2, 1).
We can calculate the slope of line l.
The formula of a slope:

Substitute:

<h3>Answer: A) -2.</h3>
There are 5280 feet in a mile:
