Question

Stan has $95. He wants to buy as many movies as he can. All movies are originally

$12.00 and are on sale for 10% off. Tax is 5%

Answer 1

Explanation:

Each movie is $12.00. 10% off of 12% is 12-1.2 = 10.8

The final amount spent is 5%, that means we can multiply the end amount spend by 1.05

The maximum Stan can spend is $95

`(10.8m)*1.05\leq 95\\(10.8m)\leq 90.4762\\m \leq (90.4762)/(10.8)\\m\leq 8.3774`

Now, you can't buy 0.3 of a movie, so the most Stan can buy is 8 movies
