(67 + 68 + 78 + x) / 4 = 70
(213 + x) / 4 = 70
213 + x = 70 * 4
213 + x = 280
x = 280 - 213
x = 67
(213 + x) / 4 = 79
213 + x = 79 * 4
213 + x = 316
x = 316 - 213
x = 103
lowest u can make is 67, highest u can make is 100
I will do my best to explain this “ x method “ I use
Basically, two factors of the first and last number must multiply together to sum up to equal the middle number
1 X 12
1 4
(x+12) (x+4)
Hope this helps!

Answer:
370 peanuts
Step-by-step explanation:
65/108 = 0.60185
90/150 = 0.6000
In each case, the number of peanuts is either exactly or very close to 60% of the volume.
A cylinder with radius 3.5 cm and height 16 cm has volume:
V = (pi)r^2h
V = (3.14159)(3.5 cm)^2(16 cm)
V = 615.752 cm^3
We take 60% of the volume to estimate the number of peanuts.
60% * 615.752 cm^3 = 369.451
Answer: 370 peanuts
