Bhavik bought 3 liters of milk and 5 loaves of bread for a total of $11. a month later, he bought 4 liters of milk and 4 loaves of bread at the same prices, for a total of $10.
how much does a liter of milk cost and how much does a loaf of bread cost?

the cost of a liter of milk is

the cost of a loaf of bread is

Step-by-step explanation:

Let

x------> the cost of a liter of milk

y------> the cost of a loaf of bread

we know that

------> equation A

------> equation B

Multiply equation A by

-------> equation C

Multiply equation B by

------> equation D

Adds equation C and equation D

Find the value of x

substitute the value of y in the equation A

answer: evaluate the objective function at each vertex to determine which - and -values, if any, maximize or minimize the function. example: find the minimum value and maximum value of the objective function f ( x , y ) = 4 x + 5 y , subject to the following constraints
