Awool sweater originally costs $42.00. if the sweater is on sale for 25% off, what is the new cost of the sweater? $

New cost of the sweater is $ 31.5 .

Step-by-step explanation:

As given

A wool sweater originally costs $42.00.

If the sweater is on sale for 25% off .

25% is written in the decimal form

= 0.25

Thus

off on a wool sweater = 0.25 × Originally costs of a wool sweater

                                 = 0.25 × $42

                                 = $ 10.5

Thus

New cost of the sweater = Originally costs of a wool sweater - off on a wool sweater.

Put all the values in the above

New cost of the sweater = $42 - $10.5

                                          = $ 31.5

Therefore new cost of the sweater is $ 31.5 .
