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?
Responses
A 5.75 kg
B 6.25 kg
C 6.75 kg
D 7.25 kg
To find the number of kilograms the pig gained each week, we can solve the equation (18 - 10)x + 30 = 80 for x.
Simplifying the equation, we have:
8x + 30 = 80
Subtracting 30 from both sides:
8x = 50
Dividing both sides by 8:
x = 6.25
Therefore, the pig gained 6.25 kilograms each week.
Answer: B) 6.25 kg
