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>

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:
Price per bottle is 1.5 or $1.50
Step-by-step explanation:
To get price per unit, you just divide the amount of money spent by the items purchased. 9/6 = 1.5
Using equations of linear model function, the number of hours Jeremy wants to skate is calculated as 3.
<h3>How to Write the Equation of a Linear Model Function?</h3>
The equation that can represent a linear model function is, y = mx + b, where m is the unit rate and b is the initial value.
Equation for Rink A:
Unit rate (m) = (35 - 19)/(5 - 1) = 16/4 = 4
Substitute (x, y) = (1, 19) and m = 4 into y = mx + b to find b:
19 = 4(1) + b
19 - 4 = b
b = 15
Substitute m = 4 and b = 15 into y = mx + b:
y = 4x + 15 [equation for Rink A]
Equation for Rink B:
Unit rate (m) = (39 - 15)/(5 - 1) = 24/4 = 6
Substitute (x, y) = (1, 15) and m = 6 into y = mx + b to find b:
15 = 6(1) + b
15 - 6 = b
b = 9
Substitute m = 6 and b = 9 into y = mx + b:
y = 6x + 9 [equation for Rink B]
To find how many hours (x) both would cost the same (y), make both equation equal to each other
4x + 15 = 6x + 9
4x - 6x = -15 + 9
-2x = -6
x = 3
The hours Jeremy wants to skate is 3.
