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.

c

step-by-step explanation:

there is vertical asymptote at x = 2 and x = 0

vertical asymptote occurs at the points where the denominator is 0. so we can say that

x = 2 occurs when there is a factor (x-2) in the denominator, and

x = 0 occurs when there is a factor "x" in the denominator

thus, the denominator of the equation would have "x * (x-2)", this is option c only. that's the correct answer.

x-150=475   x=625

step-by-step explanation:

if the bike after the sale ($150) is $475 then just simply add 150 to 475.
