Explanation of Solution

Given information:

  $1$ U.S dollar $=0.480$ pounds

  $1$ U.S dollar $=6.568$ rand

Cost of an item $=14.99$ pounds

Given

Cost of an item $=14.99$ pounds

We know

  $1$ U.S dollar $=0.480$ pounds

  $\Rightarrow$ $1$ Pound $=2.083$ U.S dollars

Cost of an item $=14.99$ pounds

Using

  $1$ Pound $=2.083$ U.S dollars

We get

  $\Rightarrow$ Cost of an item $=14.99\times 2.083$ U.S dollars
