Question

The grocery store sells kumquat for $4.50 a pound and Asian pears for $3.75 a pound write an equation in standard form for the weight of kumquat k and Asian pears p that a customer could buy with $16

Answer 1

1 pound kumquat = 4.50
1 pound pear = 3.75
4.50k + 3.75p = 16

Answer 2

let k represents the kumquat weight(in pound) and p represents the Asian pears weight respectively.

As per the given conditions,

The grocery store sells kumquat for $ 4.50 a pound

⇒ for 1 pound
`\rightarrow` $4.50

then, in k pound =
`4.50 k`

similarly,

The Asian pears for $3.75 a pound

⇒ for 1 pound
`\rightarrow` $3.75

then, in p pound =
`3.75 k`

Standard form of the equation is in the form of Ax + By = C:

The weight of kumquat k and Asian pears p that customer could buy with $ 16,

then the standard form of equation is: 4.50k +3.75p = 16
