Answer:

We must prove that (c+a)(c+d) = (b+c)(b+d)

  1. Let us use principles from mathematical induction
  2. \frac{a}{b}  =  \frac{b}{c}  =  \frac{c}{d}  = x
  3. a=bx , b=cx, c=dx
  4. a+c = b + c
  5. c +d = b + d
  6. Such that (a+c)(c+d)=(b+c)(b+d)

Josh buys cucumbers that cost $0.62 per pound.He pays $2.79 for the cucumbers.
Sphinxa [80]
Please refer to the other post you saw.

Josh's estimate IS reasonable because when you have a number 5 or above after the decimal, you round up. Although it's reasonable to round up to 5 pounds, the actual amount is 4.5 pounds, or four and a half.
