Four friends buy cinema tickets using this offer. Cinema tickets buy 3 tickets and get a ticket free they each pay £6.15 how muc

laila [671]

The cost of one ticket will be £8.20

Explanation

Suppose, the cost of one ticket is $x$

As the offer says "buy 3 tickets and get a ticket free" , it means they actually need to pay for 3 tickets.

So, the total cost of 3 tickets $=3x$

Each of four friends pay £6.15 , so the total amount they pay $=\£6.15 *4 = \£24.60$

Thus, the equation will be .....

$3x=24.60\\ \\ x=\frac{24.60}{3}=8.20$

So, the cost of one ticket will be £8.20

Vlad [161]

Answer:

19. $-\frac{5}{6}^{3}$

20. $s^{2} *7^{3}$

21. $4^{2} * b^{4}$

22. 97.2

23. 234

Step-by-step explanation:

$k^{4}*m\\ 3^{4} *\frac{5}{6}\\ 81*\frac{5}{6}=97.2$

$(c^{3}+ d^{4})^{2} -(c+d)^3\\(-1^3+2^4)^2-(-1^3+2^3)\\-1+256+1+8\\=234$

I hope this helps.
