The changs updated their bedroom by purchasing a new lamp for $89.95 and a comforter set for $239.99. they paid 6 3/5 % sales tax on their purchases. if the changs paid $351.72 total, determine if they paid the correct amount.
a. the changs family paid $0.33 too much for their purchases.
b. the changs family paid $0.99 too much for their purchases.
c. the changs family paid $5.94 too much for their purchases.
d. the changs family paid the correct amount for their purchases

  d.  The Changs family paid the correct amount for their purchases

Step-by-step explanation:

The total of the prices of the goods is ...

  $89.95 +239.99 = $329.94

Sales tax adds 6.6%, so multiplies the price by 1.066. The resulting total with tax is ...

  $329.94 × 1.066 = $351.72

This is the amount paid, so the family paid the correct amount.

the answer is; biodiversity resulting from few ancestors

adaptive radiation occurs when a population is subjected to a large natural environment with spatial ecological variations. the parts of the population in the different ecologies begin to adapt to their local environments. due to non-random mating across the large populations, this causes the different populations from the large population to speciate within their local environments. they, therefore, diverge to different species sharing a common ancestor.
