Answer:

Regular price of a ticket = $60

Step-by-step explanation:

Given:

On purchasing museum tickets in advance customers get 10% off on the regular price of ticket.

Anias paid the sale price of ticket = $54

To find the regular price of ticket.

Solution:

Let the regular price of ticket in dollars be $=x$

Discount offered for booking in advance = 10%

Discount amount in dollars = $Discount\ percent \times Regular\ price=10% \times x =0.10 \times x =0.1x$

Sale price of a ticket in dollars= Regular price - Discount amount= $x-0.1x=0.9x$

Sale price given for a ticket = $54

So, we have:

$0.9x=54$

Dividing both sides by 0.9

$\frac{0.9x}{0.9}=\frac{54}{0.9}$

∴ $x=60$

∴ Regular price of a ticket = $60

Question - Find each f(c) using synthetic substitution. f(x) =5x 5 + 10x 4 + 3x 3 + 8x 2 – 6x – 3; c = 3

SpyIntel [72]

Answer:

2157

Step-by-step explanation:

The given function is

$f(x)=5x^5+10x^4+3x^3+8x^2-6x-3$

We want to find f(c) when c=3.

This means the remainder when f(x) is divided by x-3

We perform the synthetic division:

5 10 3 8 -6 -3

5 25 78 242 720 2157

Therefore the remainder is 2157

You are right
