Answer :
Let:
x = cost of the foam fingers
y = cost of the peanuts
Tim sold 16 foam fingers (Go Ravens!) and four boxes of peanuts for $132, so:
[tex]16x+4y=132[/tex]Kevin sold 20 foam fingers and 6 boxes of peanuts and earned $190, so:
[tex]20x+6y=190[/tex]Let:
[tex]\begin{gathered} 16x+4y=132_{\text{ }}(1) \\ 20x+6y=190_{\text{ }}(2) \\ \end{gathered}[/tex]Using elimination method:
[tex]\begin{gathered} 4(2)-6(1)\colon \\ 80x-96x+24y-24y=760-792 \\ -16x=-32 \\ x=\frac{-32}{-16} \\ x=2 \end{gathered}[/tex]Replace the value of x into (1):
[tex]\begin{gathered} 16(2)+4y=132 \\ 32+4y=132 \\ 4y=132-32 \\ 4y=100 \\ y=\frac{100}{4} \\ y=25 \end{gathered}[/tex]Cost of a foam finger = $2
Cost of a box of peanuts = $25
