Answer:
Independent variable- subway cost
dependent variable- nias money ($19.50)
Step-by-step explanation:
The distance could be calculated as follows:
d =
![\sqrt{ (5-2)^{2} + (-4-3)^2} }](https://tex.z-dn.net/?f=%20%5Csqrt%7B%20%285-2%29%5E%7B2%7D%20%20%2B%20%20%28-4-3%29%5E2%7D%20%20%7D)
d =
![\sqrt{ 3^{2} + (-7)^{2}](https://tex.z-dn.net/?f=%20%5Csqrt%7B%203%5E%7B2%7D%20%2B%20%28-7%29%5E%7B2%7D%20)
d =
Answer:
A. 15 mo; $875
B. 5 mo; $250
Step-by-step explanation:
A. <em>Gym fees
</em>
Let n = no. of months
<em>Community Gym</em>: Fees = 50 + 55n
<em>Workout Gym:</em> Fees = 200 + 45n
When the fees are equal,
50 + 55n = 200 + 45n Subtract 50 from each side
55n = 150 + 45n Subtract 45n from each side
10n = 150 Divide each side by 10
n = 15
<em>Community Gym</em>: Fees = 50 + 55n
Fees = 50 + 55×15
Fees = 50 + 825
Fees = $875
<em>Workout Gym</em>: Fees = 200 + 45n
Fees = 200 + 45×15
Fees = 200 + 675
Fees = $875
After 15 mo, the fees at each gym will be equal at $875.
B. <em>Computer
</em>
Option 1: Savings = 200 + 10n
Option 2: Savings = 100 + 30n
When the savings are equal,
200 + 10n = 100 + 30n Subtract 100 from each side
100 + 10n = 30n Subtract 10n from each side
100 = 20n Divide each side by 20
n = 5
<em>Option 1</em>: Savings = 200 + 10n
Savings = 200 + 10×5
Savings = 200 + 50
Savings = $250
<em>Option 2</em>: Savings = 100 + 30n
Savings = 100 + 30×5
Savings = 100 + 150
Savings = $250
After five months, the savings by either option will be equal at $250.
