Okay so I think you go south now give me ma points
Answer:
The maximum amount that should be spent on the upgrade is $38,298,000.
Step-by-step explanation:
Let the initial purchase be <em>x</em>.
The ROI = 15% of <em>x</em> = 0.15<em>x</em>
At the end of 4 years, salvage value = 10% of <em>x</em> = 0.1<em>x</em>
<em />
Current income per day = $16 × 230 = $3680
Expected income per day = $21 × 245 = $5145
Increase in income per day = $5145 - $3680 = $1465
For 4 years (assuming a year is 365 days),
Increase in income = $1465 × 365 × 4 = $2138900
Maintenance and utility cost for 4 years = 4 × $56000 = $224000
At the end of 4 years,
ROI = $2138900 + salvage value = $2138900 + 0.1<em>x</em> - $224000
0.15<em>x</em> = $1914900 + 0.1<em>x</em>
0.05<em>x</em> = $1914900
<em>x</em> = $38298000
Answer:$32
Step-by-step explanation: So if the double pack of CD's is 20 dollars and that $4 less than 3/4 of the triple pack, then $20 + $4 = $24, then to find how much 1/4 of the cost is we divide 24 by 3, getting $8. Finally we multiple $8 by 4 to get $32, so the cost for a triple pack is $32.
Answer:
w = 2
Step-by-step explanation:
Distribute the expression and compare like terms with the simplified version.
Given
wx(3y² + 6y - 2) ← distribute parenthesis
= 3wxy² + 6wxy - 2wx
Compare coefficients of like terms with
6xy² + 12xy - 4x
Compare xy² term, then
3w = 6 ( divide both sides by 3 )
w = 2
Compare xy term, then
6w = 12 ( divide both sides by 6 )
w = 2
Compare x term, then
- 2w = - 4 ( divide both sides by - 2 )
w = 2
Hence the required value of w is 2
Answers:
- <u>24000 dollars</u> invested at 4%
- <u>18000 dollars</u> was invested at 7%
======================================================
Work Shown:
x = amount invested at 4%
If she invests x dollars at 4%, then the rest (42000-x) must be invested at the other rate of 7%
She earns 0.04x dollars from that first account and 0.07(42000-x) dollars from the second account
This means we have
0.04x+0.07(42000-x)
0.04x+0.07*42000-0.07x
0.04x+2940-0.07x
-0.03x+2940
This represents the total amount of money earned after 1 year.
We're told the amount earned in interest is $2220, so we can say,
-0.03x+2940 = 2220
-0.03x = 2220-2940
-0.03x = -720
x = -720/(-0.03)
x = 24000 dollars is the amount invested at 4%
42000-x = 42000-24000 = 18000 dollars was invested at 7%
----------------------
As a check, we can see that
18000+24000 = 42000
and also
0.04x = 0.04*24000 = 960 earned from the first account
0.07*18000 = 1260 earned from the second account
1260+960 = 2220 is the total interest earned from both accounts combined
This confirms our answers.
