Answer:
Step-by-step explanation:
<u>Mark</u>
- Initial amount - $200
- Earning - $20*j
- Saving is: S = 20j + 200
<u>Ryan</u>
- Initial amount - $350
- Earning - $15*j
- Saving is: S = 15j + 350
<u>If they get same saving, then the equations will be equal:</u>
- 20j + 200 = 15j + 350
- 20j - 15j = 350 - 200
- 5j = 150
- j = 150/5
- j = 30
The answer is 30 mowing jobs
The complete factorized expression is
(2 + 2a + 3b) (2 - 2a + 3b).
Take a look at the attachment to see how I got this solution.
Answer:
Solve one of the equations for y, take that answer and plug into the second equation in place of y. Then solve for x.
Step-by-step explanation:
Need equations if you want actual answer
We will use a Future Value Formula:
FV=PV(1 + i)ⁿ
$939 is our Present Value (PV)
.06 (6%) will be substitued for i (interest)
6 years will be substituated for "n" (numbers of periods)
FV = $939 (1 + .06) ^6
FV = 1331.989446 or rounded to <u>1331.99 balance at the end of 6 years</u>
