B) A grocery store sells bags of oranges in two different sizes. The six pound bag cost $7. What is the cost per pound. Thank you to whoever awnsers this.

Answer 1

- The eight pound orange is less expensive

- The cost per pound is 1.167 per pound

Explanation:

Solving (A):

Given

Orange 1:

`Cost= \$7`

`Pound = 6lb`

Orange 2:

`Cost = \$9`

`Pound = 8lb`

Required: Which is less expensive

To do this, we first calculate the unit price of both.

In other words, the cost per pound

`Unit\ Price = (Cost)/(Pound)`

For orange 1:

`Unit\ Price = (\$7)/(6lb)`

`Unit\ Price = \$1.167` per pound

For orange 2:

`Unit\ Price = (\$9)/(8lb)`

`Unit\ Price = \$1.125` per pound

By comparing their unit prices, we have that:

1.125 < 1.167

Hence, the eight pound orange is less expensive

Solving (b):

`Cost = \$7`

`Pound = 6lb`

Required

Determine the cost per pound

`Unit\ Price = (Cost)/(Pound)`

`Unit\ Price = (\$7)/(6lb)`

`Unit\ Price = \$1.167` per pound

Hence, the cost per pound is 1.167 per pound
