<em>AB</em> + <em>ACB</em> = <em>A</em> (<em>B</em> + <em>CB</em>) = <em>A</em> (<em>I</em> + <em>C </em>) <em>B</em>

Taking the inverse gives

(<em>A</em> (<em>I</em> + <em>C </em>) <em>B</em>)⁻¹ = <em>B </em>⁻¹ (<em>I</em> + <em>C</em> )⁻¹ <em>A</em> ⁻¹

so the answer is (A)

sdas [7]
This is not possible,  because if you had 11 coins,  then not even 11 dimes will cover it,  because 11*10 is 110,  or $1.10
