Kevin and Randy Muise have a jar containing 39 coins, all of which are either quarters or nickels. The total value of the coins in the jar is $5.75

How many of each type of coin do they have?

Value of a nickel = $0.05

value of quarter = $0.25

Now let the Jar contains 'x' number nickels as the Jar contains 39 coins, then number of quarters in Jar would be '39-x'

So, total value of nickels quarters = 5.75$

$$\Rightarrow 0.05x+0.25\times (39-x)=5.75\phantom{\rule{0ex}{0ex}}\Rightarrow 0.05x+9.75-0.25x=5.75\phantom{\rule{0ex}{0ex}}\Rightarrow 9.75-5.75=0.25x-0.05x\phantom{\rule{0ex}{0ex}}\Rightarrow 4.00=0.20x\phantom{\rule{0ex}{0ex}}\Rightarrow x=20$$

So, number of quadraters in Jar =39-x

=39-20

Number of quarters in Jar = 19

Number of Nickels in Jar =20

value of quarter = $0.25

Now let the Jar contains 'x' number nickels as the Jar contains 39 coins, then number of quarters in Jar would be '39-x'

So, total value of nickels quarters = 5.75$

$$\Rightarrow 0.05x+0.25\times (39-x)=5.75\phantom{\rule{0ex}{0ex}}\Rightarrow 0.05x+9.75-0.25x=5.75\phantom{\rule{0ex}{0ex}}\Rightarrow 9.75-5.75=0.25x-0.05x\phantom{\rule{0ex}{0ex}}\Rightarrow 4.00=0.20x\phantom{\rule{0ex}{0ex}}\Rightarrow x=20$$

So, number of quadraters in Jar =39-x

=39-20

Number of quarters in Jar = 19

Number of Nickels in Jar =20
