Answer:
![x + {4x}^{2}](https://tex.z-dn.net/?f=x%20%2B%20%20%7B4x%7D%5E%7B2%7D%20)
Step-by-step explanation:
simplify by combining like terms
4x - 3x = x
![3x ^{2} + {x}^{2} = {4x}^{2}](https://tex.z-dn.net/?f=3x%20%5E%7B2%7D%20%20%2B%20%20%7Bx%7D%5E%7B2%7D%20%20%3D%20%20%7B4x%7D%5E%7B2%7D%20)
we're left with
![x + {4x}^{2}](https://tex.z-dn.net/?f=x%20%2B%20%20%20%7B4x%7D%5E%7B2%7D%20)
Step-by-step explanation:
plan A = $25. + $0.16/min
plan B = $29 + $0.11/min
let x be no of minutes and combine both eqns...
=> 25 + 0.16x = 29 + 0.11x
=> 0.05x = 4
x = 80minutes
thus at 80mins both plans shall be equal at a cost of $37.80
