James needs 50 tons of dirt for a large construction project. he already has 3 tons of dirt at the construction site. each dump truck can transport 8 tons of dirt. how many trips does the dump truck need to take to reach 50 tons of dirt?
a.
5
b.
6
c.
7
d.
8

If he already has 3 tons of dirt at the site, He needs 50-3=47 tons to be carried by the truck
Minimum number of trips the truck will need to take=47/8
                                                                          =5.875
But since the truck cannot actually take 5.875 trips, it will take the next whole number of trips so it will take 6 trips.(B)

Step-by-step explanation:

Draw a picture. You have a right triangle with hypotenuse = 5 and one leg = 4.

length of remaining leg = √(5²-4²) = 3 ft
