First, find out how much one biscuit costs. As there are 5 biscuits, you divide the total (30) by 5. 30 / 5 = 6. One biscuit costs 6p.

Now that you know how much one biscuit costs, you times your result by 7. 6 X 7 = 42. 7 biscuits cost 42p.

mixer [17]

Answer:

$Given,\\y = 4x+1......(1)\\y = 2x^2+7x-1.............(2)\\Equating~equation (1)~and~(2),\\4x+1 = 2x^{2} +7x-1\\or, 2x^{2}+7x-4x-1-1=0\\or, 2x^{2} + 3x-2=0\\or, 2x^{2} +4x-x-2=0\\or, 2x(x+2)-1(x+2)=0\\or, (x+2)(2x-1)=0\\i.e. x=-2 ~or~ \frac{1}{2} \\When~x=2,~equation(1)~becomes ~y=4(-2) +1=-7\\When~x=-\frac{1}{2},~equation (1)~becomes~y=4(\frac{1}{2}) +1 = 2+1=3$
