A farmer grows 196 pounds of potatoes.He sells them to a grocery who divides them into 5 pound and 2 pound bags.If the grocery uses the same number of 5 pound and 2 pound bags,how many bags of each did he use?

5n+2n=196

n= 196/7

What is the prize for peppers that weigh 2.50 and cost $1.25 per pound

To determine the number of 5-pound and 2-pound bags used by the grocery, we can solve a system of equations.

Let's assume the number of 5-pound bags used is represented by 'x', and the number of 2-pound bags used is represented by 'y'.

Since the grocery uses the same number of 5-pound and 2-pound bags, we can write the equation: x = y.

Now, let's consider the weight of the bags. Each 5-pound bag weighs 5 pounds, and each 2-pound bag weighs 2 pounds.

We know the farmer grew 196 pounds of potatoes, so we can write the equation: 5x + 2y = 196.

Now we have a system of equations:

x = y
5x + 2y = 196

To solve the system of equations, we can substitute the value of 'x' from the first equation into the second equation.

Substituting x = y into the second equation, we get:

5(y) + 2y = 196
5y + 2y = 196
7y = 196
y = 196 / 7
y = 28

Now that we know y = 28, we can substitute this value back into the first equation to find x:

x = y
x = 28

So, the grocery used 28 bags of potatoes weighing 2 pounds each, and 28 bags of potatoes weighing 5 pounds each.
