So your sale would be:
35/100 times 100. So it is 35 dollars off, which means the price is now 65 dollars. Then the coupon is 12 dollars off, so 65- 12 equals 53 dollars for the fountain.

$53.

First let's find the percent off.

100*35% = 35
100-35 = 65

65-12 = 53

The final price would be $53. Hope this helps!

64, –48, 36, –27, ...<br><br> Which formula can be used to describe the sequence?
nordsb [41]

Answer:

\boxed{a_n \:  =  \: 64 \:  \times  \: ( -  \frac{3}{4} ) ^{n \:  -  \: 1} }

Step-by-step explanation:

  • We first compute the ratio of this geometric sequence.

r \:  =  \:  \frac{ - 48}{64}  \\  \\ r   \:  =  \:  \frac{36}{ - 48}  \\  \\  r \:  =  \:  \frac{ - 27}{36}

  • We simplify the fractions:

r \:  =  \:   -  \frac{3 }{4}   \\  \\ r   \:  =  \:   -  \frac{3 }{4}  \\  \\  r \:  =  \:    -  \frac{3 }{4}

  • We deduce that it is the common ratio because it is the same between each pair.

r \:  =  \:  -  \frac{3 }{4}

  • We use the first term and the common ratio to describe the equation:

a_1 \:  =  \: 64; \: r \:  =  \:  -  \frac{3 }{4}

<h3>We apply the data in this formula:</h3>

\boxed{a_n \:  =  \: a_1 \:   \times  \:  {r}^{ n \:  -  \: 1} }

_______________________

<h3>We apply:</h3>

\boxed {\bold{a_n \:  =  \: 64 \:   \times  \:  {( -  \frac{3}{4} )}^{ n \:  -  \: 1} }}

<u>Data</u>: The unknown "n" is the term you want

Answer:

\boxed{\sf{a

Step-by-step explanation:

You only need to isolate the term a to solve this problem.

Add by 3 from both sides.

\sf{\dfrac{a}{7}-3+3

Solve.

0+3=3

a/7<3

Multiply by 7 from both sides.

\sf{\dfrac{7a}{7}

Solve.

3*7=21

<u>a<21</u>

As a result, the solution is a<21, which is our answer.
