Question

14. POLITICS Mi-Ling wants to mail at least 850 fliers encouraging voters to vote for the

Answer 1

f = amount of fliers expected to be mailed in 1 day.

a)

so, she has 5 days to mail those fliers, so

day 1........... 1f mailed out

day 2........... 2f mailed out

day 3........... 3f mailed out

day 4........... 4f mailed out

day 5........... 5f mailed out

so she'll be mailing out a total of 5f fliers, we know whatever "f" is, that total must be at least 850, now, it could be more, no less, could also be 850 exactly, but could also be more, 5f ⩾ 850.

b)

$\bf 5f \geqslant 850\implies f\geqslant \cfrac{850}{5}\implies f\geqslant 170$
