Answer:
![\$30](https://tex.z-dn.net/?f=%5C%2430)
Step-by-step explanation:
we have
![p(t)=3x+2x-4x^{2}+21](https://tex.z-dn.net/?f=p%28t%29%3D3x%2B2x-4x%5E%7B2%7D%2B21)
<em>Find the amount of money that each girl spent</em>
For t= 2 hours
![p(2)=3(2)+2(2)-4(2)^{2}+21](https://tex.z-dn.net/?f=p%282%29%3D3%282%29%2B2%282%29-4%282%29%5E%7B2%7D%2B21)
![p(2)=10-16+21](https://tex.z-dn.net/?f=p%282%29%3D10-16%2B21)
![p(2)=\$15](https://tex.z-dn.net/?f=p%282%29%3D%5C%2415)
<em>Find the amount of money that they spend together</em>
Multiply by 2 the amount of money that each girl spent
![(2)\$15=\$30](https://tex.z-dn.net/?f=%282%29%5C%2415%3D%5C%2430)
