The cable provider's "triple pay" package offers a land line, internet service, and cable TV for one fixed price. If you already
Travka [436]

let x be the price before the discount

If you get 12% off, then you only pay the remaining 88% (since 88%+12% = 100%). This means if you take 88% of the original price (x), then you get the final price (132)

In terms of an equation, we have,

88% of (original price) = final price

(88/100)*(x) = 132

0.88*x = 132

0.88*x/0.88 = 132/0.88 <--- divided both sides by 0.88

x = 150

--------------------------------------------

Answer: The price without the discount is $150
