Aiden paid $30 to be a member of the Fox Lake Gym. When he takes the boxing class, it costs him$2. Noah is not a member of the Gym, and it costs him $5 for the same class. How many classes would it take for Aiden's total cost to equal Noah's total cost?

an altitude of 15,000 feet

step-by-step explanation:

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116
