Answer:

  • (A) yes
  • (B) yes
  • (C) no
  • (D) no
  • (E) yes

Step-by-step explanation:

You can go at this in different ways. In the attached, we multiplied the number of pounds by the sale price per pound ($5.25/4.2). You can also figure the price per pound of each proposed purchase and compare with the sale price.

... sale price = $5.25/(4.2 lb) = $1.25/lb

(A) $7.60/(6 lb) = $1.25/lb (yes)

(B) $4.25/(3.4 lb) = $1.25/lb (yes)

(C) $4.20/(3.5 lb) = $1.20/lb (no)

(D) $8.70/(5.8 lb) = $1.50/lb (no)

(E) $2.50/(2 lb) = $1.25/lb (yes)
