mark just bought a new vacuum cleaner for $220. he used a 30% off coupon and then paid 5.1% sales tax. what was his final cost?

MissTica

Answer: $161.85

Step-by-step explanation: $220 is the original price. you want to first deduct the 30% tax. Find out the 30% tax by multiplying 220 x .30 = 66. So deduct the $66 from $220 to get $154. That is the price. You will need to add on the 5.1% tax. So to get the tax you multiply $154 by .051 to get $7.854. Add that to the $154 sales price to get a total of $161.854. But since money, you can't have a portion of a cent so you round the 4 down

For her 1st birthday, Ruth's grandparents invested $1000 in an 18-year certificate for her that pays 10% compounded annually. Ho

Lyrx [107]

Answer:

The certificate will be worth $5,559.92 on Ruth's 19th birthday.

Step-by-step explanation:

The compound interest formula is given by:

$A = P(1 + \frac{r}{n})^{nt}$

Where A is the amount of money, P is the principal(the initial sum of money), r is the interest rate(as a decimal value), n is the number of times that interest is compounded per unit t and t is the time the money is invested or borrowed for.

In this problem, we have that:

$P = 1000, n = 1, r = 0.1, t = 18$

So

$A = 1000(1 + \frac{0.1}{1})^{1*18}$

$A = 5559.92$

The certificate will be worth $5,559.92 on Ruth's 19th birthday.
