As of Sunday evening, José has collected 172 clothing items and Biruk has collected 1 clothing item for the clothing charity drive. José says he will collect 6 items per day. Biruk says he will collect 15 items per day. How many days from Sunday will it take until they have collected the same total number of clothing items for the charity drive?

Respuesta :

Answer:

It will take 19 days from Sunday.

Step-by-step explanation:

You can use the equation 172 + 6d = 1 + 15d for this equation. 172 and 1 are how many items Jose and Biruk started with. 6d and 15d represent how many items they get a day. Here's how you can solve the equation:

172 + 6d = 1 + 15d

       -6d         -6d

        172 = 1 + 9d

           -1   -1

         171 = 9d

          ÷9    ÷9

          19 = d   (write it as d = 19)

(When you type the answer, be sure to always put the letter first.)
