Answer:
- 30 adult tickets,
- 50 kids tickets
Step-by-step explanation:
<u>Given</u>
- Cost of adult ticket = $8.50
- Cost of kids ticket = $7.00
- Number of tickets = 80
- Total cost = $605
Let the adult ticket be a and kids be k
<u>We got equations</u>
- a + k = 80
- 8.5a + 7k = 605
<u>From the first equation we get</u>
<u>Substituting k in the second equation</u>
- 8.5a + 7(80 - a) = 605
- 8.5a - 7a + 560= 605
- 1.5a = 45
- a = 45/1.5
- a = 30
<u>Then finding k</u>
Answer:
Check Explanation.
Step-by-step explanation:
The sample will be a representative of the entire build us in the city.
For a sample size 35, 3 have fire code violations, hence, the proportion of houses with fire code violations = (3/35) = 0.0857 = 8.57 %
The uncertainty in the estimate is given in the form of standard error.
Standard error = √[(p(1-p)/n]
n = sample size = 35, p = 0.0857, 1 - p = 0.9143
Standard error of the sample = √(0.0857×0.9143/35) = 0.1616
In terms of the population, (0.1616/35) = 0.00462
Proportion of buildings with fire code violations = (8.57 ± 0.462) %
Answer:
His monthly sales goal if he budgets $3750 as his monthly income is $15000.
Step-by-step explanation:
From the information given, the formula to calculate the salary that Ron earns would be:
Total salary=1500+0.15*(monthly sales)
Now, you can replace the total salary and he budgets $3750 as his monthly income and solve for the monthly sales:
3750=1500+0.15*(monthly sales)
3750-1500=0.15*(monthly sales)
monthly sales=2250/0.15
monthly sales=15000
According to this, the answer is that his monthly sales goal if he budgets $3750 as his monthly income is $15000.
