Step-by-step explanation:
Let's look at what we know. We know that...
P=2000
r=0.04 (Change 4% to a decimal)
t=7 (25 years minus 18 years equals 7)
n=1
Since we are compounding each year, we need to use this equation: 
Now just plug the numbers in: (Answer to #1:) 
This equals 2631.86
When we round, this equals to $2,632. (Answer to #2).
Answer:
Veronika's weight = 92 pounds
Kate's weight = 46 pounds
Step-by-step explanation:
Let Veronika's weight = x
Let Kate's weight = y
The sum of Veronika's and Kate's weight is 118 pounds.
x + y = 118
Veronika weighs 26 pounds more than Kate.
x = y + 26
How much do they weigh individually?
We substitute y + 26 for x in Equation 1
x + y = 118
y + 26 + y = 118
26 + 2y = 118
2y = 118 - 26
2y = 92
y = 92/2
y = 46 pounds
x = y + 26
x = 46 + 26
x = 92 pounds
Hence,
Veronika's weight = 92 pounds
Kate's weight = 46 pounds
The number of paychecks Jalen will have to save until he can purchase the laptop is 6
<h3>How many paychecks will Jalen have to save until he can purchase the laptop? </h3>
<u>Define your variable</u>
To do this, we use the following variables
- x represents the number of paychecks
- y represents the cost of the laptop
<u>Set up an equation, and solve it.</u>
In (a), we have:
- x represents the number of paychecks
- y represents the cost of the laptop
Using the above variables, the equation is:
y = 200 + 50x
The cost of the laptop is $500.
So, we have:
200 + 50x = 500
Evaluate the like terms
50x = 300
Divide by 50
x = 6
Hence, the number of paychecks Jalen will have to save until he can purchase the laptop is 6
