If each garden takes 20 minutes to clean, it will take him (20 x 4) to clean the gardens.
20 x 4 = 100
80 minutes
or 1 hour and 10 minutes.
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
X = low-energy lamp
y = high-energy lamp
1) 4x + 5y
2) 120= 4x + 5y
