Step-by-step explanation:
Hello, I can help you with this
Step one
find the profit using a simple rule of three
if
4000 ⇔ 100%
then, how much(x) is 6.94?
x ⇔ 6.94%
the relation is
the profit is 277.6
hence, her balance after one year is the initial amount plus interest earned
balance= 4000+277.6
balance= 4277.6

Answer:
Advance tickets=$25
Same-day tickets=$15
Step-by-step explanation:
Complete question below:
Suppose that there are two types of tickets to a show: advance and same-day. The combined cost of one advance ticket and one same-day ticket is $ 40. For one performance, 25 advance tickets and 30 same-day tickets were sold. The total amount paid for the tickets was $1075 . What was the price of each kind of ticket?
Let
advance tickets=x
Same-day tickets=y
Combined cost of advance and same-day tickets=$40
It means,
x+y=40 Equ (1)
25 advance tickets and 30 same-day tickets=$1075
It means,
25x+30y=1075 Equ(2)
From (1)
x+y=40
x=40-y
Substitute x=40-y into (2)
25x+30y=1075
25(40-y)+30y=1075
1000-25y+30y=1075
5y=1075-1000
5y=75
Divide both sides by 5
5y/5=75/5
y=15
Recall,
x+y=40
x+15=40
x=40-15
=25
x=25
Advance tickets=$25
Same-day tickets=$15
Check
25x+30y=1075
25(25)+30(15)=1075
625+450=1075
1075=1075
Answer:
A
Step-by-step explanation:
given
16x² + 4 = 0 ( subtract 4 from both sides )
16x² = - 4 ( divide both sides by 16 )
x² = 
= - 
[ take the square root of both sides ]
x = ± 
= ± 
i ( 
= i )
