To figure out the amount % off- 7.50×0.2=$1.5 off.
Amount with the discount- 7.50-1.50=$6
The amount with the discount with tax- 6×0.0575=$0.345
The amount with the discount plus tax- 6+0.345=$6.345 or $6.35

For the 20% off, we can make the following rule of three:

7.50 --------------> 100%

x ------------------> 20%

From here, we clear the value of x.

We have then:

[tex] x = (\frac{20}{100}) * (7.50)

x = 1.50
[/tex]

Then, subtracting both values we have:

[tex] 7.50 - 1.50 = 6
[/tex]

For taxes we have:

6 ---------------> 100%

x'---------------> 5.75%

Clearing the value of x' we have:

[tex] x '= (\frac{5.75}{100}) * (6)

x '= 0.345
[/tex]

Then, adding both values we have:

[tex] 6 + 0.345 = 6.345
[/tex]

Answer:

7.50 admission; 20% off; 5.75% tax is:

6.345
