Monte's Autorana is having an end-of-year clearance in which the TV ads proclaim that all cars are sold at 5% markup over the dealer's cost. Monte has a new Exfinity for sale
for $18,970. On the Internet, you find out that this particular model has a dealer cost of
$17,500. Is Monte being honest in his advertising?

No

Step-by-step explanation:

We first write out $17,500 as a multiplication to 5%

New price = 17500 x 1.05 = 18375  = $18,375

18375-17500 = 875

We then work out the tax on just the mark up of $875 increase

20% mark up = 875 x 0.20 = 175

18.375+175 = 18550

= $18,550 charge to be considered for 5%

However Monte would argue that tax on tax also applies to 875 x 1.20 = 1050

=$1050 and he is just asking to meet half tax costs an extra 10% of his own tax back of 17.500 x 20% that he paid = 17500 x 0.20 = 3500

tax he paid inclusive or non inclusive would be the same.

= $3500

10% of this = 3500 x 0.10 = 350  

18550+350 = 18,900

Therefore it is not dishonest if mentioned in the terms and conditions.

We also universally can round 5% up by applying other charges to include promotion costs and even apply more for administration costs.

walter needs to make at least 5 more cookies but no more than 40. 5 ≥ x ≥ 40;

step-by-step explanation:

walter has to make a minimum of 20 cookies. he already has 15 cookies made, so he must make 5 more to meet the minimum.

the maximum amount of cookies he can make is 55. he already has 15, so he has to make no more than 40 more cookies to meet the maximum.
