Question 1160938
Let m = a liter of milk
Let b = a loaf of bread
Let t = a can of tuna
5m+3b+6t = R200-R54 = R146
If a liter of milk costs R5 more than a can of tuna
m = t+5
If a loaf of bread costs R2 less than a liter of milk
b = m-2
5m+3b+6t = 146
5(t+5)+3(m-2)+6t = 146
5t+25+3m-6+6t = 146
11t+3(t+5)+19 = 146
11t+3t+15+19 = 146
14t+34 = 146
14t = 112
t = 8
m = 13
b = 11
A liter of milk costs R13 and 5 liters of milk costs R65.
A loaf of bread costs R11 and 3 loaves of bread costs R33.
A can of tuna costs R8 and 6 cans of tuna costs R48.
