To find tax you first multiply the original price x the tax(make sure to change it into a decimal)

56.35 x 0.065 =3.66

A, B & C share the rent in a ratio of 4:3:2. The rent is £216. How much does A pay?

zysi [14]

If the ratio is 4:3:2 each part of that ratio has a value of:

216/(4+3+2)

216/9=24

Since A pays four parts,

givi [52]

Answer:

Side length of each booth is 8.35 ft approximately.

Step-by-step explanation:

There are 11 companies set up equal sized square booths in a row along one wall of a convention center.

Now, refer the diagram to answer the problem.

It is given area is 1200.

So, length x width =1200

(11x+24)(x+2)=1200

Multiply using FOIL method.

$11x^{2}$ +22x+24x+48=1200

$11x^{2}$ +46x+48-1200=0

$11x^{2}$ +46x-1152=0

Solve using quadratic formula

x= $\frac{-46+/- \sqrt{46^{2}-4(11)(-1152 } }{2(11)}$

x= $\frac{-46+/-\sqrt{2116+50688} }{22}$

x= $\frac{-46+/-\sqrt{52804} }{22}$

Simplify it

$x=\frac{-49+/- 229.79}{22}$

Simplify to get two values for x.

x=8.35; x=-12.67

Here negative does not work.

Side length of each booth is 8.35 ft.
