Step-by-step explanation:

You are buying cupcakes for a school party. They are in a package of 6 for $8.50. You have budgeted no more than $40 to spend. If cost of the cupcakes is a function of the number of packages purchased, what is the largest element of the domain in this situation?

Answers

Answer: Largest element in the domain is 4

The largest number of packages you can buy is 4

======================================================

Explanation:

1 package costs 8.50*1 = 8.50 dollars

2 packages cost 8.50*2 = 17 dollars

3 packages cost 8.50*3 = 25.50 dollars

and so on. In general

x packages cost 8.50*x = 8.50x dollars

where x is a place holder for a positive whole number (1,2,3,...)

The total amount spent is 8.50x and the budget is $40

This means,

[tex]8.50x \le 40\\\\x \le \frac{40}{8.50}\\\\x \le 4.70588\\\\x \le 4\\\\[/tex]

We round down regardless of how close we are to 5.

If x = 4, then 8.50*x = 8.50*4 = 34

While if x = 5, then 8.50*x = 8.50*5 = 42.5

So we see we go over budget if we buy x = 5 packages.

This makes x = 4 the largest in the domain.

Recall the domain is the set of allowed x inputs. In this case, x is a positive whole number (since we can't buy half a package for instance).

Logan has two aquariums. One aquarium contains 1.3 cubic feet of water and the other contains 1.9 cubic feet of water. The water in the larger aquarium weighs 37.44 pounds more than the water in the smaller aquarium. Write an equation with a variable on both sides to represent the situation. Then find the weight of 1 cubic foot of water.

Answers

Answer:

62.4

Step-by-step explanation:

1. 1.3x+37.44=1.9x

2. 1.3x+37.44-1.3x=1.9x-1.3x

0.6x=37.44

3. x=37.44/0.6=62.4

The weight of 1 cubic foot of water is 62.4 lb.

Representing Equation with variable on both sides

Let 'x' pounds be the weight of 1 cubic foot of water.

We know one aquarium contains 1.3 cubic feet of water. So, the weight of 1.3 cubic feet of water = 1.3x

The other aquarium contains 1.9 cubic feet of water. So, the weight of 1.9 cubic feet of water = 1.9x

It is given in the question that the water in the larger aquarium weighs 37.44 pounds more than the water in the smaller aquarium.

The equation would be

1.9x  =  1.3x + 37.44

The above equation quality the condition of variable on both sides.

To find out the weight of 1 cubic foot of water, we will solve the above equation to find the value of x.

1.9x  =  1.3x + 37.44

1.9x - 1.3x = 37.44

0.6x  =  37.44

x = 37.44/0.6

x  =  62.4

So, the weight of 1 cubic foot of water is 62.4 lb.
