A. $1.50 / 3 = $0.50
B.
If you divide the number of peppers by $1.50, you'll get the price (rate) for one pepper.
3/1.50 =
In order to find my answer, I divided to see which price was better per pepper, the price of buying 3 peppers or 5 peppers. When I divided I found that buying the larger quantity, 5, was the better deal. It cost $.45 per pepper as opposed to $.50 per pepper.
1a. To find the unit rate, divide the group rate by the number of items in the group. Example: $1.50 / 3 = $.50
The unit rate for peppers for this stand is $.50 per pepper.
1.a. To find the unit rate per pepper, you would divide the total cost by the number of peppers.
1.b.Peppers are a better bargain at Fresh Veggies, as they cost less per unit.
A. My process was to divide the cost of peppers ($1.50) by the number of peppers. That gave me a unit price of $0.50 per pepper.
a. In order to find the unit rate, one needs to find the price for one unit, or one pepper. Since we know that three peppers costs $1.50 then we could use a proportion to calculate that the cost for one pepper or the unit rate is $0.50.
a. To find how much each pepper is I would divide 1.50 by 3, to get 1 pepper for 0.50.
b. 5:2.25 = 1:0.45, so Fresh Veggie peppers are cheaper per pepper.
c. The smaller amount per pepper is better for the consumer. Unless of course the quality of the pepper is not identical. Perhaps one stand is local organic and the other is part of the industrial produce market.
B. 0.45 vs. 0.50
C. I guess it depends one if you want 3 peppers or 5 peppers, because the price is not that different.
