Question

Kate and her brother purchased a box of fruit snacks weighing $18.5$ oz, a nacho pack weighing $13.5$ oz, and a pack of salsa weighing $3$ lbs. What is the total mass of all the items in pounds?

• A. $5$
• B. $3$
• C. $4$
• D. (a) and (c) above.

Answer 1

The correct option is A $5$

Total mass $=18.5$ oz $+13.5$ oz $+3$ lbs
$=32$ oz $+3$ lbs

Note: $1\text{lb}=16\text{oz}\Rightarrow 1\text{oz}=\frac{1}{16}\text{lb}$

So, $32\text{oz}=\frac{32}{16}=2\text{lbs}$

Therefore, total mass $=2\text{lbs}+3\text{lbs}$
$=5$ lbs
