This is called difference of squares. It's like
a^2-b^2=(a-b)(a+b)
t^2-25=(t-5)(t+5)
Hope this helps :)
The original price of concert tickets before the addition of service fee is 42.93
<h3>Percentage</h3>
- Amount spent on tickets including service fee = 45.50
- Percentage if service fee = 6%
- Original cost before service fee = x
45.50 = x + (6% of x)
45.50 = x + (0.06 × x)
45.50 = x + 0.06x
45.50 = 1.06x
x = 45.50/1.06
x = 42.9245283018867
Approximately,
x = 42.93
