Total bill would be excluding the discount, so Deens has included the discount on the wrong side of the equation.

Answer:
x = 7 cm
Step-by-step explanation:
The two triangles are similar so ...
x/(6 cm) = (42 cm)/(36 cm)
Multiplying by 6 cm, you get ...
x = (6 cm)(42 cm)/(36 cm) = (6 cm)(7/6)
x = 7 cm
The answer is 5, hope this helps
