Answer:
$12,500
Step-by-step explanation:
Using the compound interest formula Accrued Amount = P (1 + r)^n
where Accrued amount = $18000
P = principal; we need to generate it
r = 20% = 0.2
n = 2
Therefore
P = Accrued amount/ (1 + r)^n
= 18000/(1+0.2)^2
= 18000/1.44
= 12,500
hence $12,500 needs to be invested
For the general quadratic equation ax^2 + bx + c = 0 the discriminant is b^2 - 4ac.
So, for x^2 + x + 2 = 0, a = 1, b = 1, and c = 2, therefore
b^2 - 4ac = 1^2 - 4(1)(2) = 1 - 8 = - 7.
Answer: - 7
Answer:
The quick market (8 apples for $1:45)
Step-by-step explanation:
To see how much money it is for a single apple, you divide the price by the number of apples.
$1.45 divided by 8 is $0.18
$1.22 divided by 6 is $0.2
Therefore, you can buy the apples for a cheaper price at the quick market.
