Answer:
c ?
Step-by-step explanation:
Do you want this simplified?
For example a stands for the number of adult tickets, and s stands for the number of student tickets.
Write a system of equation based on the problem
An equation for "<span>A total of 679 tickets were sold for the school play"
</span>∴ a + s = 679 <em>(first equation)</em>
An equation for "<span>there were 71 fewer student tickets sold than adult tickets"
</span>∴ s = a - 71 <em>(second equation)</em>
<span>
Find the solution of the system
Subtitute s with a - 71 in the first equation to find the value of a
a + s = 679
a + a - 71 = 679
2a - 71 = 679
2a = 679 + 71
2a = 750
a = 750/2
a = 375
The number of adult tickets sold is 375</span>
Answer:
40 Operators
Step-by-step explanation:
if 10 operators worked on 120 pages for 2 hours
P operators will work on the same pages for 30min
note: 2hrs= 120min
10×120min/120= P × 30/120
- cross multiply
- make P subject of the formula
P= 10×120×120/120×30
P = 40 operators
Answer:
15,894.06
Step-by-step explanation:
HI there!
This is a compound interest question, so we will use the formula
P being our principle amount, $15,000 in this case,
R being our rate, or 1.25
N being our compound rate, which is semiannually, or twice a year.
T is our time, being 3.
After plugging these values in, we get
15,894.06
I hope this helps!
