Kisachek [45]

The total cost of Francis's purchases is $75.44.

The total cost of the purchase is the sum of the costs of the video games, taxes and the DVDs. Total cost increases by each of these items.

Total cost = tax + cost of the 2 video games + cost of the dvd

Total cost of the video games = 2 x 29.95 = $59.90

Total sales tax paid = 8% x ($59.90 + $9.95)

= 0.08 x $69.85

= $5.59

Total cost of the purchase = $59.90 + $9.95 + $5.59 = $75.44

Answer:

We know that,

10⁴ = 10000

So,

4 × 10⁴ = 4 × 10000

= 40000

So, there are 40000  honeybees in a beehive.
