Answer:
is the answer.
In decimal y = 43.71
Step-by-step explanation:
Given:
y varies directly with x .
Also x = 7 when y = 18
To Find:
y = ? when x = 17
Solution:
y varies directly with x .
i.e. y is directly proportional to x
∴ 
Where
k = constant of proportionality {Remain Same}
First we will find constant of proportionality k,
∴ When x = 7 and y = 18 we have
∴ 
Now when x= 17 and 
we have
∴
∴ 
Given:
Price paid including tax: $37.48
sales tax = 5%
This means that $37.48 is equivalent to 105%
To get the value of the 100% or its original price, we divide the price paid by its percentage rate
$37.48 ÷ 1.05 = $35.70 value of the original price
$35.70 * 5% = $1.78 value of sales tax
$35.70 + 1.78 = $37.48
