Calculation of Jam Sold

To calculate the amount of jam sold for each type, let's assign variables to the quantities mentioned in the problem:

Let x be the number of cherry jam jars sold. Let y be the number of raspberry jam jars sold.

According to the problem, the store sold 16 identical jars of cherry jam and 20 identical jars of raspberry jam. Additionally, the weight of raspberry jam sold was 8 kg more than the weight of cherry jam sold.

From this information, we can set up the following equations:

Equation 1: x + y = 16 (since the store sold 16 identical jars of cherry jam and raspberry jam combined) Equation 2: y = x + 8 (since the weight of raspberry jam sold was 8 kg more than the weight of cherry jam sold)

To solve this system of equations, we can substitute Equation 2 into Equation 1:

x + (x + 8) = 16 2x + 8 = 16 2x = 8 x = 4

Now that we have the value of x, we can substitute it back into Equation 2 to find the value of y:

y = 4 + 8 y = 12

Therefore, the store sold 4 kg of cherry jam and 12 kg of raspberry jam in one day.

Answer: The store sold 4 kg of cherry jam and 12 kg of raspberry jam in one day.
