X would equal 3 i am just guessing so its not 100%
Let us assume the number of hours volunteered by Katie = x
Number of hours volunteered by Elizabeth = y
Number of hours volunteered by Siobhan = z
After one week,
x = y + 3
z = y - 1
After 3 weeks
3x = 3 (y + z)
Dividing both sides by 3, we get
x = y + z
Putting the value of x from the first equation in the third equation, we get
x = y + z
y + 3 = y + z
z = 3
Now putting the value of z in the second equation, we get
z = y - 1
3 = y - 1
y = 4
Putting the value of y in the first equation, we get
x = y + 3
= 4 + 3
= 7
The number of hours volunteered by Katie = 7 hours
Number of hours volunteered by Elizabeth = 4 hours
Number of hours volunteered by Siobhan = 3 hours
100,000 if im correct but do some research
Answer:
$ 4,688.00
Step-by-step explanation:
I = 4000 × 0.043 × 4 = 688
I = $ 688.00
$ 688.00 + $ 4,000.00 = $ 4,688.00
