Ling is conducting a survey outside of a grocery store. the double number lime shows the ratio of customers using reusable shopping bags : costumers using plastic bags on a typical day. if there are 50 costumers that use plastic bags, how many reusable shopping bags?

Hey!
So you're kind of wanna estimate on this one,but here would be a good option:

15 - 3 = 12

Since you know that, to wanna keep adding 15 too you get 50
So 15 divided by 50 = 0.3
3 x 5 = 15

I think your final answer is going to be 15.

I really hope this helps!
Have wonderful day!! :)

Hey there,

Your correct answer would be 15.

3 x 5=15 .
