2.) A zoo is raising a young elephant. They put him on a special high-protein diet to gain weight rapidly. He gains 6 kilograms

Elena L [17]

Answer:

The weight after 20 months is 210 kilos.

Step-by-step explanation:

1 month = 6 kilos
=> 8 months = 6 x 8 = 48 kilos
=> x + 48 = 138
=> x = 90

This means that the starting point is 90 kilos.

=> 1 month = 6 kilos
=> 20 months = 6 x 20 kilos
=> 20 months = 120 kilos
=> 90 + 120 = weight in 20 months
=> 210 kilos = weight in 20 months

Hence, the weight after 20 months is 210 kilos.
