Answer:

$\$100 = 8200\ Yen$

$\$1000 = 82000\ Yen$

$\$10000 = 820000\ Yen$

Explanation:

Given

$\$ 1 = 82\ Yen$

Solving (a): Equivalent of $100

Represent this with x.

So, we have:

$\$100 = x$ and

$\$ 1 = 82\ Yen$

Cross Multiply:

$x * \$1 = 82\ Yen * \$100$

$x * 1 = 82\ Yen * 100$

$x = 8,200\ Yen$

Hence:

$\$100 = 8200\ Yen$

Solving (b): Equivalent of $1000

In (a)

$\$100 = 8200\ Yen$

Multiply both sides by 10

$10 *\$100 = 8200\ Yen * 10$

$\$1000 = 82000\ Yen$

Solving (c): Equivalent of $1000

In (a)

$\$100 = 8200\ Yen$

Multiply both sides by 100

$100 *\$100 = 8200\ Yen * 100$

$\$10000 = 820000\ Yen$
