Im kind of confused
What am i supposed to do?
1 answer:
Club A: 25+30x where x is the number of lesson
Club B 55 + 20x where x is the number of lesson
when is the cost equal
25+ 30x = 55 + 20x
subtract 20 x from each side
25+ 30x -20x = 55 - 20x
25+ 10x = 55
subtract 25 from each side
25-25+ 10x = 55 - 25
10 x = 30
divide by 10
10x/10 = 30/10
x = 3
After 3 lessons the cost is equal
