Question 576869
the coat of 3 large candles and  5 small is 6.40. the cost of 4 large candles and 6 small candles is 7.50 which pair of equation can be used to determine, t, the cost of a large candle and s, the cost of a small candle.
sol:
let t,be the cost of a large candle and s,be the cost of a small candle.
3t + 5s = 6.40--------1
4t + 6s = 7.50--------2
the above two equations help in finding t & s
