please select the best answer from the choices provided

Explanation:

Step1: Calculate 16oz unit price

Unit price = $\frac{\text{Total Cost}}{\text{Ounces}} = \frac{3.36}{16} = 0.21$ dollars per ounce

Step2: Calculate 2x10oz total cost

Total cost = $(2 \times 2.30) - 0.40 = 4.60 - 0.40 = 4.20$ dollars

Step3: Calculate 2x10oz unit price

Total ounces = $2 \times 10 = 20$ ounces
Unit price = $\frac{4.20}{20} = 0.21$ dollars per ounce

Step4: Compare unit prices

Both options have equal unit prices.

Answer:

a. Darius will get the same deal on either purchase
