Question 995497
let a garden table be {{{T}}} and a bench {{{B}}}

if the cost of the garden table is three times the cost of the bench, we have

{{{T=3B}}}

if cost ${{{1000}}} combined,we have

{{{T+B=1000}}}

{{{3B+B=1000}}}

{{{4B=1000}}}

{{{B=1000/4}}}

{{{B=250}}}=>the cost of the bench

and

{{{T=3B}}}=>{{{T=3*250}}}=>{{{T=750}}}=>the cost of the table
