Answer:
The formula used to calculate profit 'p' will be :
Step-by-step explanation:
Cost of 1 CD = $6.45
So, cost of 1000 CD's =
The selling price of 1 CD = $12.95
Let the profit be represented by 'p'
Selling price of 1 CD = $12.95
So, selling price of 'n' CD's = $12.95n
So, the formula used to calculate profit 'p' will be :
Answer:
22, 19, 16 and - 5
Step-by-step explanation:
To evaluate any term from the n th term formula substitute the terms position value for n
given = 25 - 3n, then
(a)
= 25 - (3 × 1) = 25 - 3 = 22
= 25 - (3 × 2) = 25 - 6 = 19
= 25 - (3 × 3) = 25 - 9 = 16
(b)
= 25 - (3 × 10) = 25 - 30 = - 5
Answer: 300 years
Step-by-step explanation:
Let x be the age of Florentine statue,
Thus, According to the question,
The age of Roman statue = 3 x
After 100 years, the age of Florentine statue = x + 100
And, the age of Roman statue = 3x + 100
Again according to the question,
3x + 100 = 2( x + 100)
3x + 100 = 2x + 200
3x - 2 x = 200 - 100
x = 100
Therefore, the present age of Roman statue = 3 × 100 = 300 years
