Answer:
A liter of milk cost $0.75 and a loaf of bread cost $1.75
Step-by-step explanation:
Let the liters of milk by represented by m
Let the loaves of bread by represented by b
Bhavik bought 3 liters of milk and 5 loaves of bread for a total of $11
3m + 5b = 11...... Equation 1
A month later, he bought 4 liters of milk and 4 loaves of bread at the same prices, for a total of $10
4m + 4b = 10.... Equation 2
Combining the Equations
3m + 5b = 11...... Equation 1
4m + 4b = 10.... Equation 2
We solve using the Elimination method
Multiply Equation 1 by 4 and Equation 2 by 3 to eliminate m
12m + 20b = 44..... Equation 3
12m + 12b = 30....... Equation 4
Substract Equation 4 from Equation 3
8b = 14
b = 14/8
b = $1.75
Solving for m
3m + 5b = 11...... Equation 1
3m + 5($1.75) = 11
3m + $8.75 = $11
3m = $11 -$ 8.75
3m =$ 2.25
m =$ 2.25/3
m = $0.75
Therefore,
a liter of milk cost $0.75 and a loaf of bread cost $1.75
