Last week at a tax free sale, Ms. Kuhn bought 4 shirts for $15.95 each and 2 new belts that cost $8.95 each. If she paid with a $100 bill, how much change did she receive?
$18.30
$75.10
$2490
$24.90

$18.30

Explanation:

The change is the amount left over after the selling price has been matched by the buyer.

Let us find the total cost of what of Ms. Kuhn bought;

For the shirt;

    Cost  = 4 shirts for $15.95 each  = 4(15.95) = $63.8

                2 new belts for $8.95 each  = 2(8.95)  = $17.9

Total cost  = $63.8 + $17.9  = $81.7

The amount of change left  = $100  - $81.7  = $18.3

in theory, limestone is composed principally of the compound calcium carbonate - caco3, but in reality this compound is deposited in conditions involving a number of other compounds as impurities so it ends up being a mixture of many compounds.
