<h3>
Answer: B) $1.75</h3>
===================================================
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
MAB = 360 - 255 = 105
<ADB = 1/2(mAB) = 1/2(105) = 52.5
