Harman [31]

Answer:

Step-by-step 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 $\frac{3420}{1140}=2.842$

So its around 3 days
