Answer:

Donald needs 3 days to earn 3420 dollars

Explanation:

Donald sells 760 marbles everyday. He sells each marble for 1.5 dollars

amount collected in one day=
760 \cdot 1.5=1140 dollars

In one day the amount earned is 1140 dollars

we need to find the number of days needs to earn 3420 dollars

Number of days needed is
(3420)/(1140)=2.842

So its around 3 days

Donald needs 3 days to earn 3420 dollars
