The total estimated cost with the appropriate significant figures is
$195,13.
Any two non-zero digits that are separated by a zero are important. For instance, the number 108.0097 has seven significant digits. Every zero that is both to the right and left of a non-zero digit and the decimal point is never meaningful. For instance, the number 0.00798 had three significant digits.
Simply multiply the required number of goods by their individual costs, then add them all up to calculate this:
3*13,69= 41,07 2*9,53=19,06 \s1*135= 135
Total cost: $41,07 plus $19,06 plus 135 equals $55,13.
