Answer 1

Answer: B) $1.75

===================================================

Step-by-step explanation:

To get the unit cost, we divide the total cost over the number of pounds.

We can do this for any row

• row one: ($17.50)/(10) = $1.75
• row two: ($35.00)/(20) = $1.75
• row three: ($52.50)/(30) = $1.75
• row four: ($70.00)/(40) = $1.75

You don't need to show all four row calculations. You can simply pick one row.

This tells us that each pound costs $1.75

Put another way: the price is $1.75 per pound
