1. **Problem 1:** A stand can hold 157.5 kg. How many 1.25 kg bags of potatoes will it hold? Formula: Number of bags = Total weight capacity \div Weight per bag Calculation: $$\text{Number of bags} = \frac{157.5}{1.25}$$ Simplify: $$= \frac{\cancel{157.5}}{\cancel{1.25}} = 126$$ So, the stand can hold 126 bags. 2. **Problem 2:** Jude earned 342.72. If he earned 9.52 an hour, how many hours did he work? Formula: Hours worked = Total earnings \div Hourly rate Calculation: $$\text{Hours} = \frac{342.72}{9.52}$$ Simplify: $$= \frac{\cancel{342.72}}{\cancel{9.52}} = 36$$ Jude worked 36 hours. 3. **Problem 3:** Dwight earns 12.48 an hour and works 36.5 hours a week. How much does he earn in four weeks? Formula: Total earnings = Hourly rate \times Hours per week \times Number of weeks Calculation: $$\text{Earnings} = 12.48 \times 36.5 \times 4$$ First multiply 12.48 and 36.5: $$12.48 \times 36.5 = 455.52$$ Then multiply by 4: $$455.52 \times 4 = 1822.08$$ Dwight earns 1822.08 in four weeks.
