Linear Regression is an approach for modeling the relationship between a scalar dependent variable y and one or more explanatory variables denoted x. the case of one explanatory variable is called simple linear regression
5x-2=10-3x
8x=-8
8x/8=-8/8
X=-1
10/7 = 6/x cross multiply to solve for x
<span>x=4.2 dozen cookies
</span><span>4.2 dozen cookies * 12 cookies/dozen= 50.4 cookies</span>
In order to make back the money they spent ($1,137.50) plus $1500, they want to make
$2,637.50 total.
They want to make this amount by selling 350 agendas, so divide the amount they want to make by 350 to find the amount per book:
I rounded the answer to the nearest hundredth because the hundredth is the smallest amount we have in USD (the penny.)
So they need to charge at least $7.54 to make back their money plus $1500.
Hope I helped, and let me know if you have any questions :)
