A box had twice as many grapes as a basket. Once 2 kg of grapes were added to the basket, it contained 0.5 kg more than the box. How many kilograms of grapes are in the basket now?

3.5 kg  - in a basket now

Step-by-step explanation:

x kg - in a basket

2x kg - in a box

(x + 2) - in a basket now

(x + 2) - 2x = 0.5

x + 2 - 2x = 0.5

- x = 0.5 - 2

x = 1.5

x + 2 = 1.5 + 2 = 3.5 kg - in a basket now

3.5 kg

Step-by-step explanation:

Box- 2x

Basket- x

After adding 2 kg to the basket:

x+2= 1.5+2= 3.5 kg

answer: the common difference is -0.10
