Answers

How to find the unit of rate. Well, in this case finding the unit rate would be pretty simple. All you have to do is take 14Ib and 2.99 and divide them the equation will look like this 14÷2.99=4.682274247491638796 so your answer (I think please correct me if I'm wrong and I am sooo sorry if I'm wrong) would be 4.68 or 4.6

Final answer:

The unit rate is calculated by dividing the total cost by the total weight. In this case, dividing $2.99 by 14 lbs gives us a unit rate of approximately $0.21 per pound.

Explanation:

The unit rate in this case is how much we pay for 1lb of weight. It's calculated by dividing the total cost by the total weight. So, in this instance, we would divide 2.99 (cost) by 14 (weight).

Using these numbers:

2.99 ÷ 14 = 0.213571428...

Now rounding to the nearest hundredth (as is common in currency), that gives us 0.21.

So, the unit rate for 14lbs for $2.99 is roughly $0.21 per pound.
