Answer:
Step-by-step explanation:
Each friend pays $2250/5 = $450 per month as a shared resident.
Both servings of pancakes cost $8.50
One serving of pancakes cost $4.35
Equation: 1.15 (2x + 1.50) = 11.50
2.3x + 1.725 + 11.50
2.3x = 9.725
x = 4.25 for one serving of pancakes
2x = 8.50 for both servings of pancakes
The pattern is multiplying by 3. So it will be: 243, 729
