36 sundaes and 28 banana splits were sold.
Step-by-step explanation:
Given,
Cost of one sundae = $2
Cost of one banana split = $3
Total made = $156
Let,
Number of sundaes sold = x
Number of banana splits sold = y
According to given statement;
2x+3y=156 Eqn 1
x=y+8 Eqn 2
Putting value of x from Eqn 1 in Eqn 2
Dividing both sides by 5
Putting y=28 in Eqn 2
36 sundaes and 28 banana splits were sold.
