Question

Alaina paid $8.95 for 5 pounds of nectarines. At this rate, how much would 13 nectarines cost?

I divide 8.95 by 5 to get rate per pounds = 1.79 but how do i figure out what 13 nectarines cost?

If multiple 1.79 by 13 isn't that 13 lbs not the price of 13 oranges?

Answer 1

To find the cost of 13 nectarines, you need to use the rate per pound that you calculated. Here's the process:

1. Find the rate per pound: $8.95 ÷ 5 lbs = $1.79 per pound
2. Find the weight of 13 nectarines: If you don't have information on the weight of a single nectarine, you can estimate it or use an average weight. Let's assume that the weight of a nectarine is 0.25 pounds (4 ounces). Then, the weight of 13 nectarines is 13 x 0.25 = 3.25 pounds.
3. Calculate the cost of 3.25 pounds of nectarines at the rate of $1.79 per pound: Cost = 3.25 lbs x $1.79/lb = $5.81

Therefore, 13 nectarines would cost $5.81 at the same rate that Alaina paid for 5 pounds of nectarines.
