The grocery store sells kumquats for $4.75 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 $22.

A. 4.75k+2.25p=22
B. 4.75k=2.25p+22
C. 4.75+2.25=k
D. 4.75p+2.25k=22

Since k represents the weight of kumquats in pounds and p represents the weight of Asian pears in pounds, the cost equation can be derived by multiplying the price per pound of each item by its weight and adding the total to determine the total cost:

Total cost = Cost of kumquats + Cost of Asian pears
Total cost = ($4.75 per pound)k + ($2.25 per pound)p

Since the total cost is given as $22, the equation becomes:
($4.75 per pound)k + ($2.25 per pound)p = $22

Therefore, the equation in standard form for the weights of kumquats k and Asian pears p that a customer could buy with $22 is:
A. 4.75k+2.25p=22
