Answer:
444 adult ticket
763 student ticket
Step-by-step explanation:
let a = number of adult ticket
let s = number of student ticket
s+a=1207
5a+s=2983
get s by itself in the 1st equation so you can plug it into the 2nd
s+a=1207
-a -a
s=1207-a
5a+(1207-a)=2983
solve for a
4a+1207=2983
-1207 -1207
4a= 1776
444
this is adult ticket amount
subtract this from 1207 to get student amount
1207-444=763
Answer:
Other number is 278.
Step-by-step explanation:
Given that
a + b = 981
One of the numbers = 703
We assume that it is a ; So
a = 703
Other number = b = ?
Put value of a in a + b
a + b = 981
703 + b = 981
b = 278

Step-by-step explanation:
Answer: 2
Step-by-step explanation: Rate of change is also defined as slope, so using the rise over run method, you can see that the slope of the line is +2.
For this case we have a function of the form:
y = A * (b) ^ t
Where,
A: initial amount
b: growth rate
t: time
Substituting values we have:
y = 200 * (1.10) ^ (t)
For 3 years we have:
y = 200 * (1.10) ^ (3)
y = 266.2
Rounding off we have:
y = 266
Answer:
