Answer:
9n+18(2n-6)+13
Step-by-step explanation:
First, use distributive property to eliminate the parenthesis:
9n + 18(2n -6) + 13
9n + 36n - 108 + 13
Next, combine like terms:
9n + 36n - 108 + 13
45n - 108 + 13
45n + 121
Hope this helps!!

The first washing machine is 50% off- so it'd be $260 for the final price
The second washing machine was marked down by 20%, so it'd be 416. But then it was marked down another 30% so the final price would be $291
Since the first washing machine was just 50% of $520, it's a better deal rather than 20% of $520, then 30% of $416
I hope my answer was clear enough!
The third one down, I think!!!!
