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
Answer:
Around 91.38
Step-by-step explanation:
26.5 x 100/29 = 91.38
8x - y = 54
8x + 2y = 60
subtracting, we get -3y = -6
y = 2
x = 7
Answer is (c) (7,2)
Answer:
Step-by-step explanation:
we know that
A relationship between two variables, x, and y, represent an inverse variation if it can be expressed in the form 
or 
In this problem we have
For 
-----> 
so
Find the value of k
substitute the value of x and f(x)
therefore
the equation is equal to
For 
-------> substitute in the equation and find the value of f(x)
