Simple Interest = P.R.T / 100
P = Principal (Amount invested) =$30
R = Rate= 10%
T = Time = 3 years
Therefore, Simple Interest (I):

I = ($30 * 10 * 3 ) / 100
I = $900 / 100
I = $9

When the driver is in the truck, the mass is 2948.35 kilograms, then the total mass is

Let n be the number of boxes of paper the driver must deliver at the first stop. Their weigth is 22.5n kg and the weight of the truck without n boxes is

Trucks with a mass greater than 4700 kilograms are not allowed over the bridge, thus

Hence, the driver must deliver at least 3 boxes at the first shop.
