Mindy spent $6.24 for a new binder, $1.95 for a notebook, and $5.59 for a new pack of her favorite mechanical pencils. About how much did she spend?

Mindy spent $13.78 dollars

Step-by-step explanation:

$6.24 (cost of binder) + $1.95 (cost of notebook) + $5.59 (cost of new pack of mechanical pencils) = $13.78 (dollars spent on everything she bought)

it is a. 4.2 because 7.6-3.4 gets the remaining length of 4.2. i might be wrong but i am pretty sure this is the answer.
