5S+3T=6.40
4S+6T=7.50
now solve 5S%2B3T=6.40 for S
5S=-3T%2B6.40
S=-.6T%2B1.28
plug S into
4%28-.6T%2B1.28%29%2B6T=7.50
-2.4T%2B5.12%2B6T=7.50
3.6T%2B5.12=7.50
3.6T=2.38
T=.66
now plug in .66 into
5S%2B3%28.66%29=6.40
5S%2B1.98=6.40
5S=4.42
S=.88
Small candles cost $.88 and large candles cost $.66.
