part 2: $4.60 for 20 pencils
1 pencil would cost $4.60 / 20 = $0.23
best value: part 2 (20pencil pack)

Multiply 3 to the first bracket then multiply 2 to the second bracket. 3(a+2b) + 2(3a+b) = 3a+6b+6a+2b= 9a+8b
The actual value is 250.84 .
Formula
Percentage calculation =(given value/total value)*100
let the actual value is "x"
percentage we known is 59 1/5% (59.2%) and 59.2% of x is 148.5.
for the percentage,
x*59.2% =148.5
x*59.2/100=148.5
x=(148.5/59.2)*100
x=(2.5084)*100
x=250.84
The actual value is 250.84 .

Answer : Distance between the ships to the nearest miles = 106.03 ≈ 106 mi.
Explanation :
Since we have shown in the figure below :
a=70 mi.
b=52 mi.
c=x mi.
So, we use the cosine rule , which states that
So, c = x= 106.03 mi.
Hence, distance between the ships to the nearest miles = 106.03 ≈ 106 mi.
