Kyle bought x pencils. He paid $1.24, including tax, per pencil. He gave the
cashier $20 and received $5.12 in change. How many pencils did Kyle purchase?

Respuesta :

Answer:

Kyle purchased 12 pencils

Step-by-step explanation:

p= pencils

1.24p - 5.12 = 20

or, you can do this back wards like this....

20 - 5.12 = 14.88

14.88 / 1.24 = 12

p=12

(sorry for any confusion, this is just how my brain works...)
