Answer:
$60.79
Step-by-step explanation:
First take off the 30% from $78.95. That will leave you with $55.265.
Add 6% of $78.95 for sales tax (4.737) to the $55,265 = $60.002
Then add the 1% of $78.95 for local option tax (.7895) to the $60.002.
That gives you $60.7915 - round it to the nearest cent and it gives you
$60.79
Answer:
Step-by-step explanation:
If these 3 points are collinear, then we can find the slope of the linear function using any 2 of those points. Suppose we use (-4, 3) and (0, 1):
As we move from (-4, 3) to (0, 1), x increases by 4 and y decreases by 2. Hence, the slope of this lilne is m = rise/run = -2/4, or m = -1/2.
Using the slope-intercept formula y = mx + b and replacing y with 1, x with 0 and m with -1/2, we get:
1 = (-1/2)(0) + b, or b = 1. Then the desired equation is y = f(x) = (-1/2)x + 1
