let 'd' represent the cost of the drink, then '2d' represents the cost of the bread, '4d' represents the cost of the salad and '5d' represents the cost of the laundry detergent
18 = d + 2d + 4d + 5d
18 = 12d
d = 18/12 = 1.5
2*1.5 = 3.
4*1.5 = 6.
5*1.5 = 7.5
The drink cost $1.50
The bread cost $3.00
The salad cost $6.00
The laundry determine cost $7.50
