Maybe convert 2/5 into meters
All four sides of the original square have length s.
Adding 3 to s results in s+3, the length of the resulting rectangle.
Subtracting 3 from s results in s-3, the width of the rectangle.
The area of the rectangle is (s+3)(s-3) = s^2 - 9 = 27,
and therefore s^2 = 36, and s = 6 square units.
Answer: $163.85
Explanation:
1) Data:
Purchase price: $ 113.00
mark up: 45%
2) Formula
selling price = purchase price + mark up
mark up = % * purchase price
3) Solution
mark up = 45% * $ 113.00 = 0.45 * $ 113.00 = $50.85
selling price = $ 113.00 + $ 50.85 = $ 163.85
Answer: $ 163.85
Answer:
Part 1) Slope-intercept form
Part 2) The slope of 2.20 tells me the rate per mile and the y-intercept of 2.50 tells me the flat fee
Step-by-step explanation:
Part 1) we know that
The linear equation in slope intercept form is equal to

where
m is the slope or unit rate
b is the y-intercept or initial value
In this problem we have

This is a linear equation in slope intercept form
where


Part 2) we have that
x -----> represent the number of miles
y ----> represent the total charge in dollars
The slope is
---> unit rate
The y-intercept is
----> initial value or flat fee
therefore
The slope of 2.20 tells me the rate per mile and the y-intercept of 2.50 tells me the flat fee
