The grocery store sells kumquats for $4.25 a pound and Asian pears for $2.25 a pound. Write an equation in standard form for the weights of kumquats k and Asian pears p that a customer could buy with $18.

Question

4.25 + 2.25 = k

4.25k = 2.25p + 18

4.25p + 2.25k = 18

4.25k + 2.25p = 18

Answer 1

The correct equation in standard form for the weights of kumquats \( k \) and Asian pears \( p \) that a customer could buy with $18 is:

\[ 4.25k + 2.25p = 18 \]

This equation represents the total cost of \( k \) pounds of kumquats at $4.25 per pound and \( p \) pounds of Asian pears at $2.25 per pound, equaling $18.

If you want to express it in standard form with integer coefficients, you can multiply the entire equation by 100 to eliminate the decimals:

\[ 425k + 225p = 1800 \]

This can be considered a standard form equation with integer coefficients.
