Question 805626
5S+3T=6.40
4S+6T=7.50
now solve {{{5S+3T=6.40}}} for S
{{{5S=-3T+6.40}}}
{{{S=-.6T+1.28}}}
plug S into
{{{4(-.6T+1.28)+6T=7.50}}}
{{{-2.4T+5.12+6T=7.50}}}
{{{3.6T+5.12=7.50}}}
{{{3.6T=2.38}}}
{{{T=.66}}}
now plug in .66 into
{{{5S+3(.66)=6.40}}}
{{{5S+1.98=6.40}}}
{{{5S=4.42}}}
{{{S=.88}}}
Small candles cost $.88 and large candles cost $.66.
