How Many Pens Can Alice Buy With M Dollars, If K Pens Cost N Cents?

How many pens can Alice buy with m dollars, if k pens cost n cents?

 

Answer:

Equation:

k = m ÷ n

Step-by-step explanation:

Amount of money Alice have = m

Number of pens = k

Cost of each pen = n

Total number of pens that can be bought with money on hand:

k = m÷n

Lets say:

m  = $20

n (cost of each pen) = $0.50 or 50 cents

To find how many pens(k) a $20 (m) can buy:

k = $20 ÷ $0.50

k = 40 pens
