Question 1204685


let the number of nickels be {{{n}}} and the number of  pennies {{{p}}}


if Jody has {{{2}}} more nickels than pennies, we have

{{{n=p+2}}}....eq.1



and if she has {{{30}}} coins all together, we have

{{{n+p=30}}}

{{{n=30-p}}}...eq.2


from eq.1 and eq.2 we have

{{{p+2=30-p}}}

{{{p+p=30-2}}}

{{{2p=28}}}

{{{p=14}}}


then

{{{n=14+2}}}....eq.1

{{{n=16}}}


answer: Jody has {{{16}}} nickels and {{{14}}} pennies
