The linear equation in slope - intercept form that models the total cistern of the rental over times is
y= 30x + 20
Step-by-step explanation:
100% = $70.99
there is a discount of 25%.
that means 75% (100 - 25) of the original price remains.
the equation to get any x% amount of a 100% total is simply
x% amount = 100% total amount × x/100
25% = 70.99 × 25/100 = $17.75

Define x :
--------------------------------------------------------------------------
Let Charmaine's age be x
Charmaine = x
Shaun = x + 4
--------------------------------------------------------------------------
Construct equation :
--------------------------------------------------------------------------
Sum of their age is 16
x + x + 4 = 16
2x + 4 = 16
2x = 12
x = 6
--------------------------------------------------------------------------
Find their Charamine's and Shaun's age
--------------------------------------------------------------------------
Charmaine = x = 6
Shaun = x + 4 = 6 + 4 = 10
--------------------------------------------------------------------------
Answer: Charmaine is 6 years old. (Answer B)
