Answer:
$819.48 more does he have to pay.
Step-by-step explanation:
As per the statement:
Mr. Grant's credit card bill was $2,684.72. If he has already paid off $1,865.24 of the amount due
⇒Total Credit card bill of Mr. Grant = $2684.72
Since, he already paid amount = $1865.24
We have to find how much more does he have to pay..
![\text{Amount he have to pay more} = \$2684.72 -\$1865.24 = \$819.48](https://tex.z-dn.net/?f=%5Ctext%7BAmount%20he%20have%20to%20pay%20more%7D%20%3D%20%5C%242684.72%20-%5C%241865.24%20%3D%20%5C%24819.48)
therefore, $819.48 more does he have to pay.
