Lauren got $321 from various relatives on her birthday. If she wants to put 20% of the money into her savings account, how much will she have left over to spend on new clothes?

20/100=x/321
20 x 321=100x
20 x 321=6420
6420/100=64.2

I believe the correct answer from the choices listed above is the first option. The equation that would represent the problem stated above would be 3.75k + 2.25p = 14 where k is the number of kumquats bought and p is the number of pears. Hope this answers the question.
