16. Mary and Ramon lost their jobs due to
the pandemic, so they thought of
making a facemask to make a living.
Mary sews twice as what Ramon sews
and the total facemask, they sew is 120
in one day. How many facemasks does
Mary sew? How many facemasks does
Ramon sew?
Let’s solve!

17. To find the answer to the problem, you need
to translate the word phrase into
Mathematical expression or equation.
Let us use variables to represent the
number of facemasks. Since the total
number of facemasks, they sew in a day is
given, represent the number of facemasks
each sews.
Let’s solve!

18. Let
x be the number of facemask Ramon
sew
2x be the number of facemask Mary
sew, since she sews twice as Ramon
sew
Let’s solve!

19. To translate word phrases into
