Pencils sell for 98 cents per dozen. How much more per pencil does it cost to buy 5
for 50 cents?
0.98 / 12 = 0.08 each
0.5 / 5 = ______ each
oops - Ms Sue did it right. I was calculating the cost per dozen, not each.
The answer is 1.83.
I'm still not sure how to get it.
Can someone please walk me through this
0.98/12= 0.081
.50/5=0.1
To determine the cost difference per pencil, we need to compare the cost per pencil when buying a dozen pencils at 98 cents to the cost per pencil when buying 5 pencils for 50 cents.
First, let's calculate the cost per pencil when buying a dozen pencils:
The price of a dozen pencils is 98 cents.
There are 12 pencils in a dozen.
So, the cost per pencil when buying a dozen pencils is 98 cents / 12 pencils = 8.17 cents per pencil.
Now, let's calculate the cost per pencil when buying 5 pencils for 50 cents:
The price of 5 pencils is 50 cents.
So, the cost per pencil when buying 5 pencils is 50 cents / 5 pencils = 10 cents per pencil.
To find the difference in cost per pencil, subtract the cost per pencil of buying 5 pencils from the cost per pencil of buying a dozen pencils:
8.17 cents per pencil - 10 cents per pencil = -1.83 cents per pencil.
Therefore, it costs 1.83 cents less per pencil when buying a dozen pencils at 98 cents compared to buying 5 pencils for 50 cents.
well, 50¢/5 = 10¢ each.
So, how much does a dozen cost at that rate?
