Answer:
Part A: 7n + 30= -5 and 8n + 40= 16
Part B: 7(8) + 30= 86 and 8(8) + 40= 104
Part C: Company A saves you 12.
Step-by-step explanation:
Company A: 7n + 30
Company B: 8n + 40
7n + 30= -5 8n + 40= 16
7(8) +30= 86 8(8) +40= 104
7(2) + 30= 44 8(2) + 40= 56
56 - 44= 12
Answer:
The function will be: f(n) = 2n
Step-by-step explanation:
An arithmetic sequence is a sequence where the common difference between consecutive terms is same
The sequence according to given information is:
2,4,6...
Here
a_1 = 2
a_2 = 4
a_3 = 6
the common difference will be:

The arithmetic sequence is given by:

Putting the values

Hence,
The function will be: f(n) = 2n
Answer:
Correct option: (A) 43.48% fall in the price of a ticket.
Step-by-step explanation:
The price elasticity of demand is defined as the percent change in quantity demanded to the percent change in the price.

Given:
Price elasticity of demand = 0.23
% change in quantity demanded = 10
Compute the % change in price as follows:

Thus, a 10 percent increase in attendance can be explained by a 43.48% fall in the price of a ticket.
Answer:

Step-by-step explanation:
Solving inequalities is just like solving equations. Isolate x and whatever you do to one side, you must do to the other.
1) First, isolate the term with the x. To get rid of the -5, add 5 to both sides.

2) Next, isolate the variable x by dividing both sides by -2. However, remember that when working with inequalities, you must flip the inequality sign when dividing or multiplying by a negative number. Thus, the greater than sign becomes a less than sign.

Thus, the answer is
.
