V= (4x2) x (2x) x (2x^2+x +7)
8 (2x) (2x^2+x+7)
V= 32x^3 +16x ^2 +112 x
You can also factor out an x and a 16
By the 7th week, 2,187 people will have found out the secret.
a) The slope of the line relating Alyssa's sales to earnings is given by
slope = (change in earnings)/(change in sales)
Using the first two table entries, the slope is calculated as
slope = (110 -80)/(200 -10) = 30/200 = 0.15
The first entry in the table shows the y-intercept, the value of earnings (80) for zero sales. The slope-intercept form of the equation for a line is
y = slope*x + y-intercept
To answer the first question, we put the slope and intercept values in the appropriate spots in the equation.
The equation that gives Alyssa's daily earnings based on her total sales is
y = 0.15x +80
b) The y-intercept of the line represents the part of Alyssa's earnings that doesn't depend on sales. It is Alyssa's fixed daily wage.
c) The slope of the equation represents Alyssa's commission rate.
d) The y-intercept is 80.
Answer:
so $21+45%=30.45. meaning that pair of boots cost 30.45 so two pairs of boots would cost $60.90
