Answer

Explanation:

Step1: Calculate cost per ml in vending machine

$1.25\div355\approx0.003521$ (dollars per ml)

Step2: Convert volume of grocery - store carton to ml

$1.89\times1000 = 1890$ ml

Step3: Calculate cost per ml in grocery store

$3.89\div1890\approx0.002058$ (dollars per ml)

Step4: Calculate savings per ml

$0.003521 - 0.002058=0.001463\approx0.0015$ (dollars per ml)

Answer:

You would save approximately $0.0015$ dollars per ml.

Explanation for part B:

Step1: Calculate total cost of carton of 12

$34.68 + 5.45=40.13$ dollars

Step2: Calculate cost per unit of carton of 12

$40.13\div12\approx3.3442$ dollars per unit

Step3: Calculate total cost of carton of 18

$51.30+6.25 = 57.55$ dollars

Step4: Calculate cost per unit of carton of 18

$57.55\div18\approx3.1972$ dollars per unit

Step5: Calculate difference in cost per unit

$3.3442 - 3.1972 = 0.147\approx0.15$ dollars per unit

Answer for part B:

The carton of 18 is a better buy. It is approximately $0.15$ dollars cheaper per unit.
