A truckload of apples weighs 2550 lbs. If 5 (exact) apples weigh 1250 g, how many apples are in the truck?

egoroff_w [7]

Answer:

There are 4,626 apples in the truck.

Explanation:

Mass of 5 apples = 1250

Mass of an apple = $\frac{1250 g}{5}=250 g$

Mass of apples in the truck = 2550 lbs

1 lbs = 453.592 g

$2550 lbs=2550\times 453.592 g$

Let the number of apples with mass of 2550 lbs be a.

$a\times 250 g=2550\times 453.592 g$

$a=\frac{2550\times 453.592 g}{250 g}=4,626.63$

4,626.63 ≈ 4,626

So, there are 4,626 apples in the truck.
