Question 155272
Let x = the value of the 1945 nickel, then the value of the 950 nickel is {{{(4/3)x}}} and their sum is $28, so...
{{{x+(4/3)x = 28}}} Simplify.
{{{(7/3)x = 28}}} Multiply both sides by {{{3/7}}}
{{{x = 12}}}
The value of the 1945 nickel is $12.00
The value of the 950 is {{{(4/3)(12)}}} = $16.00
