Question

Donald sells 760 marbles every day. He sells each marble for 1.5 dollars. For how many days does Donald need to sell marbles to ear 3420 dollars?

Answer 1

Hello!

First of all, let's find out how much he earns each day. We multiply our marbles by their cost.

760(1.5)=1140

This gives us the equation below.

1140x=3420

We divide both sides by 1140.

x=3

Therefore, he needs to sell marbles for 3 days.

I hope this helps!

Answer 2

3 Days

(in case you need to show your work)

760*1.5= 1,140

1,140*3= 3,420
