Starting at 2:15

1 Hour would be 3:15pm
5 Hour would be 7:15pm
8 Hour would be 10:15pm
10 Hour would be 12:15pm

Since 10 Hours gets us too far over our final time we'll use 9 hours

9 Hours gets us to 11:15pm

adding 30 minutes gets us to 11:45 pm
and adding 5 more minutes gets us to our final time of 11:50pm

All in all it takes 9 Hours 35 Minutes from 2:15 pm to 11:50 pm

x+3=17\\

The manager of a snack bar buys bottled water in packs of 35 and candy bars in packs of 20. Then, she sells the items individual

hoa [83]

Answer:

8 packs of bottled water and 14 packs of candy bars

Step-by-step explanation:

Provided,

Each pack of water bottles = 35 bottles

Each pack of candy = 20 candy

Since quantity of candy in each pack is small than quantity of water bottle in each pack, in order to have same quantity in numbers of both bottles and candies,

Purchase quantity of candy packs shall be more than the pack of water bottles.

Further, with this option 1 and 2 are not valid as candy packs are same or less than packs of water bottle.

In option 3 and 4, option 3 have smaller quantities as provided manager bought the least possible quantity.

Accordingly

Option 3

8 packs of water bottle = $8 \times 35 = 280 \ water\ bottles$
