Case bought a 10 week old pig that weighed 30 kg. At 18 weeks the pig weighed 80 kg. The equation (18-10)x+30=80 can be used to find the number of kg (x) the pig gained each week. How many kilograms did the pig gain each week

Answer 1

To find the number of kilograms the pig gained each week, we need to solve the equation:

(18-10)x + 30 = 80

Simplifying the equation, we have:

8x + 30 = 80

Subtracting 30 from both sides, we get:

8x = 50

Dividing both sides by 8, we find:

x = 50/8

Calculating this division, we have:

x = 6.25

Therefore, the pig gained approximately 6.25 kilograms each week.
