A month later, he bought 4 44 liters of milk and 4 44 loaves of bread at the same prices, for a total of $ 1 0 $10dollar sign, 10. How much does a liter of milk cost, and how much does a loaf of bread cost? A liter of milk costs $ $dollar sign and a loaf of bread costs $ $dollar sign .

Answer 1

3m + 5b = 11.....multiply by 4
4m + 4b = 10....multiply by -3
---------------------
12m + 20b = 44 (result of multiplying by 4)
-12m - 12b = -30 (result of multiplying by -3)
--------------------add
8b = 14
b = 14/8
b = 1.75 <=== the bread costs $ 1.75 per loaf

4m + 4b = 10
4m + 4(1.75) = 10
4m + 7 = 10
4m = 10 - 7
4m = 3
m = 3/4
m = 0.75 <=== and a liter of milk costs 0.75

Answer 2

The cost of 1 liter milk is $ 0.75 and the cost of a loaf of bread is $1.75
