To control her blood pressure, Jill's grandmother takes one half of a pill every other day. If one supply of medicine contains $60$ pills, then the supply of medicine will last approximately

$1$ month

$4$ months

$6$ months

$8$ months

$1$ year

Solution:

She takes half a pill every two days, so one pill lasts $4$ days. Then $60$ pills last $60 \times 4 = 240$ days.

At about $30$ days per month, that is roughly $240 \div 30 = 8$ months.

Thus, the correct answer is D .
