4 × 3
−−−− = 6cm²
2
6 × 3 = 18cm²
10 × 5 = 50cm²
50 + 18 + 6 = 72cm²
A store advertises "Buy one and get one half off"
Which means if we buy one, half the price of one will be discounted.
In other words "50% discount on each item we buy"
Original cost of skates = $88
After 50% discount price of one skate = $88 - $44 = $44
Cost of 10 pairs of skates = 44 × 10
= $440
Therefore, we will pay $440 for 10 skates.

Answer:
Step-by-step explanation:
To find the inverse function for y = f(x), solve the equation ...
x = f(y)
x = 2y +1 . . . . . . . use the function definition
x-1 = 2y . . . . . . . . undo the addition of 1 (subtract 1)
(x -1)/2 = y . . . . . undo the multiplication by 2 (divide by 2)
The inverse function is ...
f⁻¹(x) = (x -1)/2
