Question

The prices for various numbers of pounds of apples at several stores are shown in the table below

Answer 1

Option B

Explanation:

At Jerry's Fresh Produce,

Per pound price of apples =
`\frac{\text{Total cost}}{\text{Total weight of apples}}`

=
`(10.25)/(5)`

= $2.05

Cost of 7 pounds of apples = 7 × 2.05 = $14.35

At Parson's Market,

Per pound cost of apples =
`(11.34)/(6)`

= $1.89

Cost of 7 pounds of apples = 7 × 1.89

= $13.23

At Carlo's Apple Orchard,

Cost of one pound apples =
`(15.44)/(8)`

= $1.93

Cost of 7 pounds of apples = 7×1.93

= $13.51

At Ed's Green Grocery,

Cost of one pound of apples =
`(18.99)/(9)`

= $2.11

Cost of 7 pounds of apples = 7 × 2.11

= $14.77

By comparing all prices we find at Parson's Market cost of 7 pounds of apples is $13.23

Option B is the answer.
