Question

Aiden is grocery shopping and wants to know which packages are cheapest. He is
looking at four different bottles of liquid laundry detergent: Bottle A is 175 fluid
ounces for $19.25; Bottle B is 138 fluid ounces for $8.97; Bottle C is 100 fluid ounces
for $8.00; and Bottle D is 72 ounces for $7.56. Assuming the detergent is of equal
quality, which bottle is the best deal?

Answer 1

Answer:Bottle B

Step-by-step explanation:

Given

Bottle A has 175 fluid ounce and cost $\ 19.25$

So it cost $\frac{175}{19.25}=9.09\ \text{ounce per}$

Bottle B has 138 fluid ounce and cost $\ 8.97$

So it cost $\frac{138}{8.97}=15.38\ \text{ounce per}$

Bottle C has 100 fluid ounce and cost $\ 8.0$

So it cost $\frac{100}{8}=12.5\ \text{ounce per}$

Bottle D has 72 fluid ounce and cost $\ 7.56$

So it cost $\frac{72}{7.56}=9.52\ \text{ounce per}$

So, Bottle B delivers more ounces at same price
