Question

The number of flour packets needed to bake one pizza on Sunday is 4 less than two times the number of flour packets needed to bake one pizza on Saturday. If the number of flour packets needed for one pizza on Saturday is “$m$”, then find the number of flour packets needed on Sunday to bake 5 pizzas.

• A. $2m-4+5$
• B. $2m-4$
• C. $5(2m-4)$
• D. $5(2m+4)$

Answer 1

The correct option is C $5(2m-4)$

Number of flour packets needed to bake one pizza on Saturday $=m$
Two times the number of flour packets needed on Saturday $=2m$
The number of flour packets needed to bake one pizza on Sunday is four less than two times the number of flour packets needed to bake pizzas on Saturday.
So, the number of flour packets needed for 1 pizza on Sunday $=2m-4$
So, the number of flour packets needed on Sunday to bake 5 pizzas $=5\times (2m-4)$
$=5(2m-4)$
Option A is correct.
