Question 1203956


Jeff, Tom, and Chelsea order a large pizza. They decide to split the cost according to how much they will eat. 

let  the pizza cost be {{{x}}}

Tom pays ${{{5.16}}}
Chelsea eats {{{1/8}}} of the pizza, => have to pay {{{(1/8)x}}}

and Jeff eats {{{1/2}}} of the pizza,=> have to pay {{{(1/2)x}}}

then

{{{x=5.16+(1/8)x+(1/2)x}}}

{{{x=5.16+(5x)/8}}}

{{{x-5x/8=5.16}}}

{{{8x/8-5x/8=5.16}}}

{{{3x/8=5.16}}}

{{{3x=5.16*8}}}

{{{3x=41.28}}}

{{{x=41.28/3}}}

{{{x=13.76}}}


the pizza cost ${{{13.76}}}
