2 | ($25 x 2) = $50 | ($11 x 2 + 18) = $40 | Profit = $50 - $40 = +$10
| ---- | -------- | -------
3 | ($25 x 3) = $75 | ($11 x 3 = 18) = $51 | Profit = $75 - $51 = +$24

Total Number of toys = 1+2+3 = 6
Total Earnings = $25+$50+$75 = $150
Total Cost = $29+$40+$51 = $120
Total Profit = $150-$120 = +$30

Answer: the future value of the investment is $53399.8
Step-by-step explanation:
We would apply the formula for determining compound interest which is expressed as
A = P(1+r/n)^nt
Where
A = total amount in the account at the end of t years
r represents the interest rate.
n represents the periodic interval at which it was compounded.
P represents the principal or initial amount deposited
From the information given,
P = $22,000
r = 6% = 6/100 = 0.06
n = 2 because it was compounded 2 times in a year.
t = 15 years
Therefore,
A = 22000(1 + 0.06/2)^2 × 15
A = 22000(1 + 0.03)^30
A = 22000(1.03)^30
A = $53399.8
Answer:
Base = 17
Height = 5
Step-by-step explanation:
(4x + 1)(x + 1) = 85
4x² + 4x + x + 1 = 85
4x² + 5x - 84 = 0
∆ = 5² - 4.4.(- 84)
∆ = 25 + 1344
∆ = 1369
x = (- 5 + 37)/8
x = 32/8
x = 4
Base = 4.4 + 1 = 17
Height = 4 + 1 = 5
