Answer: 5,800 $15 tickets, 1,800 $25 tickets
Explanation
x= the first type of ticket
y= second type of ticket
First add x and y to equal total of tickets.
x+y= 7600
Next add 15x and 25y to equal total cost.
15x+25y=159,000
So we have
x+y= 7600
15x+25y=159,000
Let’s use the substitution method to get our answers. So lets arrange the equations and different way.
x= 7600-y
15x+25y=159,000
Now let’s substitute the x into the second equation.
15(7600-y)+25y= 159,000 *Distribute 15*
114,000+25y= 159,000 *Subtract
114,000*
25y= 45,000 *Divide 45,000 by 25*
y=1,800
Now let’s replace y with 1,800 to get our x
x+1,800= 7600*Subtract 1,800 from 7,600*
x= 5,800

Answer:
x = -5
Step-by-step explanation:
-x = 5
*-1 *-1
-x * -1 = x
5 * -1 = -5
x = -5
Answer:
35
Step-by-step explanation:
Given
n (A) = 15
n (B) = 20
Students who do not like any subject = 5
Hence, number of students who would like either both or either of the two subjects = 60-5 = 55
n (A or B) = n (A) + n (B) - n (A and B)
Number of students linking both the subjects
55 - 15-20
= 55-35 = 20
Number of students linking only one subject = 60-20-5 = 35
