Question 697925

the original price of the necklace was ${{{x}}}

and {{{70}}}% off is {{{(70/100)x=0.70x}}}

that was equal to ${{{110}}};

so, the original price of the necklace ${{{x=110+0.70x}}}....solve for {{{x}}}

${{{x-0.70x=110}}}

${{{x(1-0.70)=110}}}

${{{x(0.30)=110}}}

${{{x=110/0.30}}}

${{{x=366.66666666666666666666666666667}}}

${{{x=366.67}}}

check:

{{{70}}}% off ${{{x=366.67}}} is ${{{366.67*0.70=256.67}}}, then subtract it from the original price ${{{366.67-256.67=110}}} which is discounted price
