laila [671]

Answer:

The best value is \$ 180 for 15 calendars.

Step-by-step explanation:

Lets find out the unit cost of each calendars with different prices given here.

  • The price of 6 calendars is \$ 114.

Unit cost of these calendars = \frac{114}{6} = \$ 19

  • The price of 8 calendars is \$ 144.

Unit cost of these calendars = \frac{144}{8} = \$ 18.

  • The price of 10 calendars is \$ 160.

Unit cost of these calendars = \frac{160}{10} = \$ 16.

  • The price of 15 calendars is \$ 180.

Unit cost of these calendars = \frac{180}{15} = \$ 12.

  • The price of 20 calendars is \$300.

Unit cost of these calendars = \frac{300}{20} = \$ 15.

So the best value from customer point of view is the lowest unit cost.

And the lowest cost is being offered for 15 calendars \ @\ 12\$ per calendar.
