Given:
Package A
Birthday cards = 3
Thank you notes = 2
Costs = $18
Package B
Birthday cards = 8
Thank you notes = 6
Costs = $50
Required:
x = birthday card cost
y = thank you notes cost
Solution:
Package A:
18 = 3x + 2y
Package B:
50 = 8x + 6y
Second, add the two equations using elimination method.
To find y eliminate x;
[8 (18 = 3x + 2y)] + [-3 (50 = 8x + 6y)]
(144 = 24x + 16y) + [-150 = -24x + (-18y)]
-6 = -2y
Divide both sides with -2.
y = 3 thank you notes cost
Next, let us find x by substituting the value of y.
(18 = 3x + 2y) + (50 = 8x + 6y)
[18 = 3x + 2(3)] + [50 = 8x + 6(3)]
(18 = 3x + 6) + (50 = 8x + 18)
68 = 11x + 24
68 – 24 = 11x
44 = 11x
Divide both sides with 11.
X = 4 birthday card cost
We all, as human beings, have social and environmental responsibility. Regarding social responsibility, we need to pay for the services we receive in society and we need to work to contribute to society our ideas and the benefit of our skills, training and education to help move society forward. Regarding the environment, with the advent of global warming and more and more serious consequences of it like the extreme wildfires in British Columbia, Canada and the devastation of Hurricanes Harvey and Irma, we need to do our part to reduce greenhouse gases-like using electric buses or bikes to get to work for example. Also, we need to reduce garbage especially in our cities so that our garbage doesn't have to be exported to small communities in the country who don't want the extra liability and also by recycling so that waste can be reused, to help that resources do not have to be used up to make more waste products and pollute the environment in the process.
