I don't know. But where I live, bananas are $.19/lb.
Here's how you can do it without any math:
At 5 oz each, there are about 3 bananas (a little more than 3) in a pound.
At 69¢ a pound ( = 3+ bananas), one banana costs a little less than 23¢.
3 bananas @ 5 oz ea = 15 oz (almost 1 lb)
3 bananas @ 23¢ ea = 69¢
Answer:
One banana costs about $0.22 (which is a little less than $0.23)
1 lb = 16 ounces
Amount paid for average banana
= [(0.69 cents) / (16 ounces)] × (5 ounces)
= 0.215625 cents
≈ 0.22 cents (to 2 decimal places)
We know that,
1 lb = 16 ounces
Paid amount
= [(0.69 cents) / (16 ounces)] × (5 ounces)
= 0.215625 cents
1$ = 100 c.
Average banana price 5 oz
= $0.69 / lb * 1 lb / 16 oz
= 5 * $0.69 / 16 oz = $0.22.
$0.22 * 100 c / $1 = 22 c.
You're paying 22 c average banana.
At the market, bananas cost $2.76 for 4 lbs.
If the average banana weighs 5 ounces,
how much are you paying for the average banana.
1 pound = 16 ounces
The cost of 64 ounces is $2.76.
The cost of an average banana weighing 5 ounces is $0.21(25).
.69 x 5/16 ... before sales tax
