Kamila buys a notebook for $1.59 and pens for $0.29 each. She spends $5.07.

emmasim [6.3K]

Answer:

12 pens

Step-by-step explanation:

Let the variable that can be used to determine the number of pens that Kamila bought be represented by n.

Price of a notebook = $1.59

Price a pen = $0.29

Total amount spent = $5.07

But,

1.59 + 0.29 n = 5.07

So that,

0.29 n = 5.07 - 1.59

0.29 n = 3.48

n = $\frac{3.48}{0.29}$

= 12

Therefore, Kamila bought 12 pens.
