Solution:

Concept:

This is a direct currency conversion problem using a given exchange rate.

Explanation:

From the exchange rate,

\mathrm{N}1.00 = \$0.075

.

Let the cost in Naira be

x

.

Then,

\$0.075 \times x = \$15{,}000.00

.

So,

x = \frac{15{,}000}{0.075}

.

x = 200{,}000

.

Therefore, the engine costs

\mathrm{N}200{,}000.00

.
