Question

Rainn goes to walmart to buy school supplies. she buys a backpack for $7.99 and some spiral notebooks for for $0.79 each. after buying the backpack, how many notebooks can rainn buy with her $20 budget?

Answer 1

First, we need to know how much money Rainn has left after buying the backpack. So, to calculate this quantity, we subtract $7.99 from $20, as:

$20 - $7.99 = $12.01

Now, she has $12.01 for spiral notebooks. So, to calculate how many notebooks can Rainn buy we need to divide $12.01 into $0.79 as:

$\frac{12.01}{0.79}=15.2$

Therefore, she can buy 15 notebooks

Answer: 15 notebooks
