Using the Distributive Property
An electronics company sells two types of headphones. The in-ear model
costs $50. The over-the-ear model costs $100.
Store A
Store B
Store C
The table shows how
many units of each model
Stores A, B, and C want to
buy.

1. How can the Distributive Property and mental math be used to find the total
amount the company receives from the three stores for the in-ear
headphone model?

people went from manufacturing one object at a time by hand to manufacturing many objects in factories

6 hours 48 min

company a

step-by-step explanation:

using the linear regression models , it is found that company a   pays about $14 more. but using the same regression (linear) company b pays about $10 more.

so company a pays more than b

2 equivalent expressions to represent the area of a rectangle and the top is n-3 and the side is 2

area of the rectangle = length * width

given length = n - 3

width = 2

replace it in the area

so area of the rectangle = (n-3) *2

= 2(n-3)

one of the expression is 2(n-3)

to get another expression we distribute 2 inside the parenthesis

2(n-3) is 2n - 6

so another expression is 2n - 6

two equivalent expression are

2(n - 3)   , 2n - 6
