Question

So far in this course, you have seen real-life applications of linear equations, linear inequalities, and linear systems. In your initial post to this forum, create a word problem related to your major for each of these three concepts. Review the applications in the text and the video lectures for ideas. You will also find many examples on the Internet as well.
In the post, include the following:

My major is Baking and Pastry, so all three concepts have to deal with Baking and Pastry. Whether it be ingredients, or so on.

Write the three word problems including their solutions - here's a chance to be creative!
Thank you!

Answer 1

om Solidion 1. Example Lucy has Boughts Two doughnuts and a chocolate cake. She has paid 2.10 dollars In the same Bakery, Jeremy has Boughts a doughnut and three chocolate cakes, He has paid 3.05 dollars How much is a doughnut and a chocolate Cake in this Bakery To Find out, we will need of linear Equations a system X= price of a doughnut and the price of a chocolate Cake y = price of a chocolate cake 2x + y = 2.1 x + 3y = 3.05 Ita system of Two equation with Two variables. 1st method: y = 2.1-2X 2x+y=2.1 x+3y=3.05 = x+3y=3.05 y - 2.1-2x y = 2.1-2X X+ 3(201-2x) = 3.05 -SX = -3.25

2 y = 2.1-2x =) y = 2:1-2 (0.65) x = 0.65 y = 0.8 X=0.65 y=0.8 2nd method: 2x + y = 2.1 2x + y = 2:1 x+3y=3.05 2x+6y= 6:1 -sy=-4 y = 0.8 2x+0.8= 2.1 x = 0.65
