Me with this question because i do not understand.

A 10% booking fee is added to the ticket price (I'm guessing 10% is added for each ticket)

Find 10% of the adult and child ticket:

10% of 15 = 1.5

10% of 10 = 1

find the total price for the 4 adult tickets he buys and 2 child tickets:

(15 +1.5) × 4 = 66

(10 + 1) × 2 = 22

66 + 22 = 88

1.5% will then be added if he lays by credit card :

1.5% of 88 = 1.32

total :

88 + 1.32 = 89.32

He pays a total of £89.32

x= -3

step-by-step explanation:

step 1: simplify brackets

4 - x - 1 = 6

step 2: simpilfy

3 - x = 6

step 3: subtract 3 from both sides

-x = 6 - 3

step 4: simpilfy 6 - 3

-x = 3

step 5: multiply both sides by -1

x = -3
