Which equation models this problem?



Susan paid $36.90 for nine washcloths. What is the unit price, p, per washcloth?



A.36.90p = 9




B.p/9 = 36.90




C.p/36.90 = 9




D.9p = 36.90



Answer :

It's D. 9 washcloths x the price (P) = 36.90

apologiabiology
so unit price times #of cloths=final price

unit price times 9=36.90
so 9x=36.90
divide both sides by 9
x=4.10

so D is the right answer
