After buying 10 pens, she had $14.30 left. How much did each pen (p) cost? (Hint: The cost for the pens can be represented by 10p. Add that to the amount left after buying the pens and you get the total amount she had to spend $26. The equation would be 14.30 + 10 = 26.)

Sagot :

Answer:

Let the price of a pen be x.

Explanation:

10*x+ 14.30= 26

⇒ 10x= 26- 14.30

⇒ 10x= 11.7

⇒ x= 11.7/10

⇒ x= 1.17
