Question:
At a pharmacy, a $2 voucher was given for every $15 spent. Mary bought 3 bottles of shampoo and 2 bars of soap. Each bar of soap costs 2/3 as much as 2 bottles of shampoo. Mary realised that she had to spend another $6.45 to get exactly $8 worth of vouchers. What was the cost of 1 bar of soap?
