48+56=104; 170-104= 66. The librarian needs to pack 66 more books.
Answer:
A
Step-by-step explanation:
$355:5
$355 divided by 5=$71
5 divided by 5=1
$71 per week
$71x15.5=$1,100.50
$1,100.50 in 15.5 weeks
It's 46.9 cause 4 is under 5 and the tenth in decimal is the first number after the decimal point.
