Question

Gerad's DVD club charges a $10 annual fee and then $2 per DVD purchased. Karen's DVD club charges a $15 annual fee and then $1 per DVD purchased. After purchasing how many DVDs will Gerad and Karen pay the same amount?​

Answer 1

Answer: 5

Explanation:

Gerad - y = 2x + 10

Karen - y = x +15

2x + 10 = x + 15

x = 5
