Question 882887
{{{3T+2B=9.50}}}
{{{5T=3B}}}
Multiply the first equation by {{{5}}}.
{{{15T+10B=47.5}}}
Substitute from the second equation,
{{{5T=3B}}}
{{{15T=9B}}}
So,
{{{9B+10B=47.5}}}
{{{19B=47.5}}}
{{{B=2.50}}}
Then,
{{{5T=3(2.50)}}}
{{{T=1.50}}}
SO then the cost of 1 of each would be,
{{{B+T=2.50+1.50=4.00}}}
