• A. 1 packet of cement that weighs 20 lb
• B. 5 packets of cement, each weighing 64 oz
• C. Cannot be determined
• D. Both offers the same deal

Answer 1

The correct option is D Both offers the same deal

$\text{One 20 lb packet of cement costs}$ $\text{the same as five 64 oz packets}$$\text{of cement.}$

$\text{First of all, we will have to convert}$ $\text{pounds to ounces.}$

$\text{We know that,}$
$\text{1 pound =}$ $\text{16 ounces}$


$\text{Hence, we will divide 64 by 16.}$

$\text{So, 64 oz}=\frac{64}{16}\text{lb}$

$=\text{4 lb}$

$\text{Now, let's calculate the weight of}$ $\text{5 packets.}$

$\text{4 lb}\times 5\text{= 20 lbs}$

$\text{Since the weight of one 20 lbs packet}$ $\text{is same as five 64 oz packets, thus,}$$\text{both offers the same deal.}$
