Answer:
The Line p
y= 3/4x+ 6.25
Step-by-step explanation:
The points given changed 4 right and 3 up, giving a slope of .75
plug this slope into (1,7) to get the y-intercept. This shows the intercept at 6.25.
Answer:
It annually drops by 20%
Step-by-step explanation:
30,000 multiplied by 20% is 6000. Subtract 6000 from 30,000 and you get 24,000. 24,000 multiplied by 20% is 4,800. Subtract 4,800 from 24,000 and you get 19,200. Etc.
Answer:
22 and a half weeks
Step-by-step explanation:
We are told that Nilda owes $250 and has been earning $25 per week to catch up and start saving.
Also, Karla has saved $200 and has been saving an extra $5 per week to slowly build her savings.
Let the number of weeks they save for be represented as x.
Therefore, for them to have the same amount of money after x weeks,
25x - 250 = 200 + 5x
The left hand side represents Nilda's situation (250 is being deducted because she owes $250) while the right hand side represents Karla's situation (the 200 is added because she already owns $200).
Solving for x:
25x - 250 = 200 + 5x
Collecting like terms:
25x - 5x = 250 + 200
20x = 450
x = 450 / 20 = 22.5 weeks
Hence, they would both need to save for 22 and a half weeks to have the same amount of money.
