Question 84057
Hello there,

I don't like snakes, but I like math so for 3, could you please clarify the question. Do they just want "a linear equation for the number of snake eyes" or a linear equation for the number of snake eyes per specific area? 

8. A linear equation is in the form of y = x. Y is called the dependent variable, because it depends on x, which is the independent variable. Your profit is Y because it depends on how many packages gets delivered (x).

So we have:

Profit = Money made from packages - 78 (Truck usage fee or something)

$36 = 4.1x - 78 <-- Each package costs 4.1 to deliver so 4.1x determines how many packages are delivered.


4.1x = 114

x &#8776; 27.805

However, courriers don't generally deliver fractions of packages so we round x up to 28. Therefore, Midtown delivery service needs to deliver 28 packages if they want to make a profit of $36 while charging $4.1/package.

Please write back to clarify #3 and if you need any more help.

Hello again,

I was curious as to whether #3 had more information because according to the question, "recorded 9 snakes on 21 acres in one area and 13 snakes on 47 acres in another area" is useless information.

Anyways, the ratio of snakes: acres are not proportional in both areas so for the first area, the linear equation of the number of snake eyes would be:

2(9y) = 21x

y = (21x/9) x 2 <-- x 2 because each snake has two eyes

Try to find the linear equation for the second area yourself. Y is the number of snake eyes.
