Given:
five times a number = 5x
decreased by 8 = 5x - 8
is at most 10 = maximum is 10 so less than or equal to 10
more than twice the number = greater than 2x.

2x < 5x - 8 <u><</u> 10

5x - 8 <u><</u> 10
5x - 8 > 2x

****

5x - 8    <u><</u> 10      if x = 3.60 then 2x < 5x-8 <u>< </u>10
     + 8      +8                              2(3.6)  < 5(3.6) - 8 <u><</u> 10
5x         <u><</u>  18                                7.2    < 10 <u><</u> 10
÷5              ÷5
        x   <u><</u>  3.60

5x - 8     > 2x                  x > 2.67; if x = 3
 
   +8             + 8                        2x < 5x - 8 <u>< </u>10
5x          > 2x + 8                        2(3) < 5(3) - 8 <u>< </u>10
-2x           -2x                                 6 < 7 <u>< </u>10
3x          >         8
÷3                    ÷3  
x             >  2.67

42 is the answer

Explanation:
50% of 80 is half of 80 which is 40

Then you would add 40 with 5% of 40

What you would do then is 5% times 40 then you would change the 5% into a decimal which is 0.05 and multiply it by 40 , which would get u 2

Then you would add the price with tax
40+2 = 42
