Three-quarters 29441

Peter bought a calculator. He saved three-quarters of its price himself, and half of the remaining amount was given to him by his grandfather. He still lacked 7 euros, which he borrowed from his brother. How much did the calculator cost?

Correct answer:

x =  56 Eur

Step-by-step explanation:

3/4x+(x3/4x)/2+7=x  3/4 x+(x3/4 x)/2+7=x  0.5x=28  x=0.528=56  x=56=56 Eur
