The Area is the width<span> times the </span>height<span>: A = w x h;
Then, 64 = w x h;
h = 4 + w;
64 = 4w + w^2;
w^2 + 4w - 64 = 0;
We solve this equation: w1 </span>≈ 6,24 > 0 (okay); w2 ≈ - 10,24 < 0 (not okay);
<span>Finally, h1 </span>≈ 10,24;<span>
</span>
Well here's your answer straight <u><em>he must pay 29.82$ </em></u>and here's my work,
- 20% of 35 is 7 and since its 20% off we must subtract 35-7=28
- Next it said there's a 6.5 tax so that means we are adding on to 28$
- 6.5 of 28 is 1.82 so we add 28+1.82 which equals your answer 29.82
Answer:

288/2=144
Half of the people bought tickets at $1.50, $1.50 times 15 equals $22.50
The other half bought them at the regular price of $2.75, $2.75 times 15 equals $41.25
When we combine the two money totals, we end up with a grand total of $63.75
