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.

Question

What equation could we write to represent that the number of pounds of flour and the number of pounds of sugar weighed a total of 16 pounds? Let f represent the number of pounds of flour and s represent the number of pounds of sugar.

Answer 1

To represent the total weight of flour and sugar in the order, we can use the following equation:

\[ f + s = 16 \]

where:

• \( f \) represents the number of pounds of flour,
• \( s \) represents the number of pounds of sugar.

This equation indicates that the sum of the pounds of flour and the pounds of sugar equals 16 pounds.
