Given that Mari went to an amusement park where she spent all her money which was $80. There she played two type of games.
Given that cost of playing "Ring Toss" game once = $4
Let She played "Ring Toss" game x times.
Then total cost for x ring toss games = 4x
Given that cost of playing "Three point shooting contest" once = $8
Let She played "Three point shooting contest" y times.
Then total cost for y "Three point shooting contest" = 8y
Now total spenditure will be sum of both which is given by (4x+8y)
Given that she spend $80 completely so both will be equal.
Hence required equation will be 4x+8y=80.
