flour costs $0.75 per pound and sugar costs $0.50 per pound. an order of flour and sugar weighs 16 pounds and costs $9. what equation could we write to represent that the total cost of the flour and the sugar in the order is $9? let f represent the pounds of flour and s represent the pounds of sugar in the order.
Answer
Explanation:
Step1: Determine cost of flour
The cost of flour per - pound is $0.75$ and the number of pounds of flour is $f$, so the cost of flour is $0.75f$.
Step2: Determine cost of sugar
The cost of sugar per - pound is $0.50$ and the number of pounds of sugar is $s$, so the cost of sugar is $0.50s$.
Step3: Set up total - cost equation
The total cost of the order is $9$. The total cost is the sum of the cost of flour and the cost of sugar. So the equation is $0.75f + 0.50s=9$.
Answer:
$0.75f + 0.50s = 9$
