The Murphy family spend $ 700
Solution:
Given that,
Murphy family has 4 members and they went to 7 games
Let "x" be the cost of each game
Murphy family cost: [tex]4 \times 7 \times x = 28x[/tex]
Chen family has 5 members and they went to 4 games
Chen family cost: [tex]5 \times 4 \times x = 20x[/tex]
In total, the two families spent $1200
Therefore,
28x + 20x = 1200
48x = 1200
Divide both sides by 48
x = 25
How much did the Murphy family spend?
Murphy family cost = 28x = 28(25) = 700
Thus murphy family spend $ 700
