We can create an equation to find the total cost of anyone who uses the car wash:

\sf y=5.09+0.60x

Where 'y' is total cost and 'x' is the minutes they spent washing the car. Plug in what we know:

\sf y=5.09+0.60(9)

Multiply:

\sf y=5.09+5.40

Add:

\sf y=\boxed{\sf \$10.49}

So she was charged $10.49.

the initial price of a home entertainment system is $34,000. It is discounted by 10% and then by a further 26%. Find the price o
maria [59]
The final price of the item is $22,644

The initial discount of 10% leaves the price at 90% of the retail value:
\frac{x}{34000}  =  \frac{90}{100}
cross multiply to solve for x:
100x = 3,060,000
x = 30,600
This new price is then discounted 26%, which means the final price is 74% of $30,600:
\frac{x}{30600}  =  \frac{74}{100}
cross multiply to solve for x:
100x = 2,264,400
x = 22,644
The final price of the home entertainment system is $22,644
