Answer: The correct option is (D) $21.77.
Step-by-step explanation: Given that Heather has $45.71 in her savings account and she bought six packs of markers to donate to her school. Each pack of markers cost $3.99.
We are to find the amount of money that she has in her bank account after the donation.
Cost of 1 pack of marker = $3.99.
So, the cost of six packs of marker = $(3.99 × 6) = $23.94.
Since there was $45.71 in her savings account before the donation, so the amount of amount of left after the donation is given by
[tex]A_l=\$(45.71-23.94)=\$21.77.[/tex]
Thus, the required amount of money left in her saving's account after the donation is $21.77.
Option (D) is CORRECT.
