A pizza parlor owner knows they sell 3 slices of cheese pizza out of 20 total slices sold. Predict how many slices of cheese pizza will be sold if the pizza parlor sells 5680 total slices in a week.

To predict how many slices of cheese pizza will be sold, we will first calculate the proportion of cheese pizza slices sold to the total slices.

Proportion of cheese pizza slices = 3 slices / 20 slices = 0.15

Now, we will use this proportion to predict the number of cheese pizza slices sold if the total slices sold is 5680.

Predicted number of cheese pizza slices sold = 0.15 * 5680 = 852

Therefore, the pizza parlor owner is predicted to sell 852 slices of cheese pizza if they sell a total of 5680 slices in a week.
