Answer:
$14
Explanation:
Let the price of 1 month of game play = x.
The price of 1 software package = 25
Angie:
1 software package + 4 months
Since 1 month costs x, 4 months cost 4x.
Angie spent:
25 + 4x
Kenny:
1 software package + 6 months
Since 1 month costs x, 6 months cost 6x.
Kenny spent:
25 + 6x
Combined, Angie and Kenny spent:
25 + 4x + 25 + 6x = 10x + 50
Their total cost was $190, so
10x + 50 = 190
Subtract 50 from both sides.
10x = 140
Divide both sides by 10.
x = 14
