Given:

The values of the US dollar (x) and a foreign currency (y) vary directly according to the formula:

y=2.5x

To find:

The number of units of the foreign currency would someone receive in exchange for 150 US dollars.

Solution:

We have,

y=2.5x

Substitute x=150 in the given formula.

y=2.5(150)

y=375

Therefore, 375 units of the foreign currency would someone receive in exchange for 150 US dollars.
