Question

Nadia buys boxes of crackers that each has the same cost c. She represents the cost of 6 boxes of cheese crackers, 5 boxes of poppys seed crackers, and 5 boxes of plain crackers using the expression 6c + 5c + 5c. What equivalent expression can represent the cost.

Answer 1

I believe the answer is b because u need to combine like terms and 6c+2c+5c is 13c.

Answer 2

To Find :-

• The equivalent expression that represents the cost .

Solution :-

Here according to the question ,

$\longrightarrow Cost \ of \ each \ crackers \ = \ c$

And , she purchases ,

$\longrightarrow \textit{ boxes of cheese crackers = 6 } \\\\\longrightarrow\textit{ boxes of poppy's seed crackers = 5 }\\\\\longrightarrow \textit{ boxes of plain crackers = 5 }$

And she represents cost by ,

$\longrightarrow Cost = 6c + 5c + 5c$

To find equivalent , take out c as common ,

$\longrightarrow Cost = c (6+5+5)$

Add the constant terms inside the brackets ,

$\longrightarrow Cost = c \times 16$

Multiply ,

$\longrightarrow \underline{\underline{Cost = 16c }}$

Hence the equivalent expression is 16c .
