A restaurant charges $6.50 for a slice of pizza that is 1/3 of a pizza and four dollars for a slice that is 1/5 of a pizza one day they cooked four pizzas that were all the same size if they sell the slices would they make more money by slicing each pizza into thirds or fifths

Respuesta :

They would make more money by slicing each pizza into fifths

Step-by-step explanation:

The given is:

  • A restaurant charges $6.50 for a slice of pizza that is 1/3 of a pizza
  • It charges four dollars for a slice that is 1/5 of a pizza
  • One day they cooked four pizzas that were all the same size

We need to know  if they sell the slices they would make more money by slicing each pizza into thirds or fifths

∵ The restaurant cooked 4 pizzas that were all the same size

- If they slicing each pizza into thirds, that means each pizza is

   divided into 3 equal slices

∵ Each pizza is slicing into 3 equal slices

∴ The number of slices = 4 × 3 = 12 slices

∵ The price of each slice = $6.5

- Multiply 12 by 6.5 to find their cost

∴ The total charge of the slices = 12 × 6.5 = 78

The total charge of the 4 pizzas is $78

- If they slicing each pizza into fifths, that means each pizza is

   divided into 5 equal slices

∵ Each pizza is slicing into 5 equal slices

∴ The number of slices = 4 × 5 = 20 slices

∵ The price of each slice = $4

- Multiply 20 by 4 to find their cost

∴ The total charge of the slices = 20 × 4 = 80

The total charge of the 4 pizzas is $80

∵ $80 > $78

∴ The total charge of the fifths is greater than the total charge

   of the thirds

They would make more money by slicing each pizza into fifths
