The cost of Nate's dinner including a 15% tip was $43.70. What was the cost of dinner alone?

The cost of dinner alone was $37.145

Step-by-step explanation:

15%=0.15Convert your percentage into a decimal

43.70*0.15=6.555Multiply the cost of dinner with the decimal

$43.70-$6.555=$37.145Subtract the last number(6.555) from the total(43.70) to get the cost of dinner alone of $37.145 -This is making you subtract the percentage from the total!

I hope this helped!

n=9

step-by-step explanation:

7 times a number = 7n

decreased by 13 = 7n-13

same as is =

5 times the number = 5n

increased by 5 = 5n+5

7n-13 = 5n+5

2n=18

n=9

what is the question? i am guessing you are looking for the area.

to find an area, you have to do length x width.

in this case, it would be 12 ft x 4 ft = 48 sq. ft
