Question

The grocery store sells kumquats for $4.75 a pound and Asian pears for $3.00 a pound . Write an equation in standard form for the weight of kumquats k and Asian pears p that a customer buy with $14

Answer 1

The standard form for the weight of kumquats k and Asian pears p that a customer buy with $14 is written as

4.75k + 3.00p = 14

Explanation:

Let k = the weight of a kumquat in pounds which the grocery store sells

Let p = the weight of Asian pears in pounds which the grocery store sells.

The grocery store sells kumquats for $4.75 a pound and Asian pears for $3.00 a pound.

k pounds of kumquat will cost k × 4.75 = 4.75k

p pounds of Asian pears will cost p × 3.00 = 3.00p

A standard form for the weight of kumquats k and Asian pears p that a customer buy with $14 will be

4.75k + 3.00p = 14
