If 1/a, 1/b, 1/c are in Arithmetic Progress, show that 2ac/a+c.

Iteru [2.4K]

1/b-1/a = 1/c-1/b [ since they are in arithmetic progress]
1/b+1/b = 1/c+1/a
2/b = (a+c)/ac
2ac = b(a+c)
2ac/(a+c) =b

An American tourist visits South Africa with $3000. The exchange rate when she arrives is

algol [13]

9514 1404 393

Answer:

$2505.80

Step-by-step explanation:

After the first exchange, the tourist has ...

$3000(12.90 R/$) = R38,700

After 7 days, she has ...

R38,700 -7(R900) = R32,400

After the second exchange, she has ...

R32,400 × ($1/R12.93) = $2505.80

She gets $2505.80 at the second exchange.
