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. \( \frac{p}{9} = 36.90 \)

C. \( \frac{p}{36.90} = 9 \)

D. \( 9p = 36.90 \)

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

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

The equation that models the problem is 9 p = 36.90 , which represents the total price paid for 9 washcloths. This corresponds to option D. To find the unit price, you would divide the total price by the number of washcloths.
