<h3>The graph shows the relationship between the total cost and the number of erasers bought at the student store. Which statement is true?</h3>
Generally, A cost is the worth of the money that has been spent in the process of producing something or delivering a service, and as a result, it is no longer accessible for use.
This concept is utilized in manufacturing, research, retail, and accounting. In the world of business, a cost may refer to a purchase, in which case the sum of money spent on the item in question is considered to be the cost of the item.

Let C = cost to rent each chair Let T = cost to rent each table
4C + 8T = 73
2C + 3T = 28
Multiply the 2nd equation by (-2) then add the equations together
4C + 8T = 73
-4C - 6T = -56
2T = 17
T = 17/2 = 8.5 Plug this in to the 1st equation to solve for C
4C + 8(17/2) = 73
4C + 68 = 73
4C = 5
C = 5/4 = 1.25
cost to rent each chair is $1.25
cost to rent each table is $8.50
Answer: B
Step-by-step explanation:
- If we add the numbers up, (47.6 + 7.32 + .0574 + 6) We get a answer of 60.9774.
Answer:
The first question would likely be y=10.
The second question would likely be x=20.
Answer:
37
Step-by-step explanation:
Margin of error = critical value × standard error
For 98% confidence, CV = 2.326 (from t table).
Standard error is σ / √n, where σ is the population standard deviation, and n is the sample size.
Plugging in:
5 = 2.326 × 13 / √n
n = 36.6
Rounding up, n = 37.
