Ivenika [448]

Ballpoint pens cost $1.50 a dozen for the first 200 dozen a store buys from a wholesaler.

$1.25 a dozen for those bought in addition to the first 200 dozen.

we have been asked to find

If the store buys 250 dozen pens from the wholesaler, then what is the average cost of ballpoint pens per dozen.

Average cost per dozen=\frac{362.5}{250}= 1.45dollars

How many black keys would you expect to find on a keyboard with 72 keys in all? Show your work.
Black_prince [1.1K]

Answer:

50 black keys

Step-by-step explanation:

for every set of 7 white keys there are 5 black keys

72/7 = 10

so there is a total of 10 full sets of keys

then you have 2 white keys remaining but that doesn't matter because they will just be on the dies and already have a black key next

so this means that you only have to calculate the number of 10 sets of black keys and thats 5 x 10.

hope this helps : )
