Answer:
The linear equation can be written as
Step-by-step explanation:
Given that "Mr. Malone can heat his house in the winter by burning three cords of wood, by sing natural gas, or by combination of the two"
And his heating budget for the winter is $600
To find a linear equation that describes the problem:
Let the cords of wood be x and let sing natural gas be y
So that the combination of the cords of wood and sing natural gas is x+y
Now the linear equation can be written as
Answer:
Step-by-step explanation:
I'm tentatively changing my answer to say this kind of relies on practical knowledge of how stores tend to operate. If 20 coupons are given out, the store has sold all 500 shirts, arguably at a loss to the retailer. They have to have more shirts in stock to be sold at full price because, well, that's how they make money. It's more likely that such a store would carry more than just 500 shirts at the start of each day, so A is (probably) wrong.
